What is indicated about the slope of a line that slants down from left to right in a rectangular coordinate system?
It shows that the variable shown on the vertical (y) axis falls as the one on the horizontal (x) axis increase. The exact nature of that relationship depends on whether the line is straight or curved.
A ball rolls off the edge of a horizontal tabletop. 4.23 ft high it strikes the floor at the point 5.11 ft horizontal away from the edge of the table for how long was the ball in the air?
Ignoring air resistance, any falling object falls 4.23 feet in the first 0.513 second.The horizontal distance doesn't matter, and we don't need to know it. The time it takes to hitthe floor after it rolls off the edge has nothing to do with how fast it was rolling before it fell.
A ball rolls off a table and falls 80 m to the floor landing with a speed of 4.5 ms What is the magnitude of the acceleration of the ball just before it strikes the ground?
It's 9.81m/s since vertical acceleration is always constant.
What is construction area and built up area?
Depending on the regulatory law in your location (Counrty/State/City) this may vary. Where I am from, the construction area can have two meanings: 1. The common: An area where construction work is being commenced 2 Technical (depending on regulatory law and how it defines it): The horizontal area that can be constructed. Built-up area: 1. Common: An area that is built (in some countries, nothing is considered built unless cement/bricks are used) 2. Technical: The total contsructed Area, horizontal and vertical in meter/feet square. Example (regarding Technical meanings): a land lot of 1,000 m.sq. that falls into, let's say Zone A, where Zone A allows 60% construction area, will then have: 600 m.sq construction area, (let's say 3 floors were built, all 3 of 600m.sq) with a total built-up area of 1,800 m.sq.
What is the number that falls in the upper1 4?
The i that falls on the top is called the numerator.
What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
What are the two types of motion a projectile has?
If you throw ball at an angle above horizontal, you will see the path of the ball looks like an inverted parabola. This is result of the fact that the ball's initial velocity has a horizontal and vertical component. If we neglect the effect of air resistance, the horizontal component is constant. But the vertical component is always decreasing at the rate of 9.8 m/s each second. To illustrate this, let the initial velocity be 49 m/s and the initial angle be 30˚. Horizontal component = 49 * cos 30, Vertical = 49 * sin 30 = 24.5 m/s As the ball rises from the ground to its maximum height, its vertical velocity decreases from 24.5 m/s to 0 m/s. As the ball falls from its maximum height to the ground, its vertical velocity decreases from 0 m/s to -24.5 m/s. Since the distance it rises is equal to the distance it falls, the time that it is rising is equal to the time it is falling. This means the total time is equal to twice the time it is falling. This is the reason that the shape of the ball's path is an inverted parabola. At the maximum height, the ball is moving horizontally. If you do a web search for projectile motion, you will see graphs illustrating this.
If something like an animal flying through the sky with horizontal velocity drops an object will the dropped object have horizontal velocity Or just vertical velocity?
It will have both horizontal and vertical velocity...think about it, if you were said bird flying through the sky at say 35 mph, and you dropped a rock then the rock would fall, but it would still be moving forward and it would fall the same way a baseball falls after it reaches the top of the throw.
How do you use a protractor when you draw an angle of 75?
Draw a straight horizontal line, and a vertical line in the middle of it. Now line these up the the lower edge of your protractor, with the vertical line in the middle of your protractor (at the 90 degree marking). Now, find the 75 degree marking on the protractor, and mark on the piece of paper where it falls. Draw a line from centre of your horizontal line, to the mark of where 75 degree is. You're done!
How high are the Della Falls in British Columbia?
the falls are a vertical drop of about 440 meters.
A bullet fired horizontally over level ground hits the ground in 0.5 seconds If it had been fired with twice the speed in the same direction it would have hit the ground when?
Assuming no affects from air and a smooth geography, both bullets would fall at the same rate of 9.81 m/s^2 toward earth, and hit the ground simultaneously. You have to look at the bullet's velocity as having a horizontal and vertical velocity vectors. The vertical velocity vector is independent from that of the horizontal. The horizontal vector would be the speed at which the bullet is fired, and the vertical vector is the speed at which the bullet falls due to gravity.
In the absence of air friction does the horizontal component of a projectile's velocity change as the projectile moves is this True False?
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
What is indicated about the slope of a line that slants down from left to right in a rectangular coordinate system?
It shows that the variable shown on the vertical (y) axis falls as the one on the horizontal (x) axis increase. The exact nature of that relationship depends on whether the line is straight or curved.
What happens to the motion of a thrown Object here on earth?
If thrown directly upwards, it slows down due to gravitational attraction and aerodynamic drag. It reaches a maximum height and then falls. Its rate of descent is accelerated by the earth's gravity but decelerated by aerodynamic drag. If thrown at an angle, it follows a trajectory in which the vertical motion is accompanied by horizontal motion which is decelerated by aerodynamic drag.If you disregard drag, then the vertical motion is symmetrical: at any height the speed going up is exactly the same as the speed on descent. Also, for a body thrown at an angle, the trajectory is a parabola.
Does the horizontal velocity of a ball affect how fast it falls?
No. The force depends only on the height of the ball and on the mass of the ball. The force due to the earth's gravitional field varies inversly with the distance from the center of the earth to the center of the ball.
