A ball is thrown with a speed of 20 ms at an angle 60 degrees above the horizontal how high does it rise?
sin(60) =.866
20m/s*.866 = 17.32m/s in the vertical direction.
x=17.32t - 9.81t2
x=0 when the ball returns to its original height, so 17.32t = 9.81t2
17.32=9.81t
t=1.766sec for the ball to return to its original height. 1/2 this time will be its maximum height.
T=.883 sec.
maximum height = 17.32t - 9.81t2 = 14.4109 - 6.807 = 7.6039 m
What else can I help you with?
A roller coaster moves 200ft horizontally it rises 135ft at angle of 30degrees above horizontal It travels 135ft at angle of 40degrees below horizontal What is displacement from start point to end?
420 feet at about an angle of -3 degrees.
What is the name of the angle above 90 degree?
An angle above 90 but less than 180 degrees is an obtuse angle An angle above 180 degrees is a reflex angle
What angle has the same horizontal displacment as 20 degrees?
20 degrees is a measure of angular displacement. This cannot be converted to lateral (horizontal) displacement.
A ball is thrown with a velocity of 40 meters per second at an angle above the horizontal. If the ball attains its maximum range what was the value of the angle?
At 45 degrees. Yay! I got a proof done, check the link below, back to studying derivations for a infinite line of charge, ewww. The Related Question may answer yours. (See below left.)
A rock is thrown from the edge of the top of a 100-ft tall building at some unknown angle above the horizontal The rock strikes the ground a horizontal distance of 160 ft from the base of the buildin?
To determine the angle at which the rock was thrown, we can use projectile motion principles. The vertical height of the building (100 ft) will dictate the time it takes for the rock to fall, while the horizontal distance (160 ft) gives us the horizontal velocity. By solving the equations of motion for both vertical and horizontal components, we can calculate the initial velocity and angle of launch. However, without additional information such as the initial speed, we cannot find a unique solution for the angle.
A ball is thrown into the air at angle of 45 degrees at what point is the total velocity the greatest?
The velocity is greatest at two points:1). when it leaves the hand of the tosser2). when it returns to the same height as it was when it was releasedThis answer is the same for any angle above horizontal, regardless of the angle.
A roller coaster moves 200ft horizontally it rises 135ft at angle of 30degrees above horizontal It travels 135ft at angle of 40degrees below horizontal What is displacement from start point to end?
420 feet at about an angle of -3 degrees.
What angle a projectile thrown to achieve maximum horizontal distance traveled?
A trajectory of 45 degrees elevation gives the longest horizontal travel- (not taking air drag into consideration nor any aerodynamic properties of a projectile.
Why javelin is thrown at 45 degree angle?
The javelin is ideally thrown at a 45-degree angle to maximize its horizontal distance. This angle allows for an optimal balance between vertical lift and horizontal distance, utilizing the forces of gravity and aerodynamic lift effectively. While the actual optimal angle can vary based on factors like speed and technique, 45 degrees serves as a theoretical benchmark for achieving maximum range in projectile motion.
What is the name of the angle above 90 degree?
An angle above 90 but less than 180 degrees is an obtuse angle An angle above 180 degrees is a reflex angle
What angle should a ramp be?
Fifteen degrees from the horizontal.
Will a ball thrown almost horizontally go the furthest?
No, this is an example of projectile motion. You should throw it at 45 degrees from the horizontal ground for it to have the maximum horizontal distance. This is because a sufficient height must be achieved, so that the ball can stay in the air longer and thus travel a longer distance while in flight.
What does 160 degree angles look like?
An obtuse angle is an angle between 90 degrees and 180 degrees. A 180 degree angle is a straight horizontal line. So you can imagine that a 160 degree angle is almost but not quite horizontal.
What angle has same horizontal displacement as 25 degrees?
65
What is a nonverticle line?
It is a line that is not at an angle of 90 degrees to the horizontal!
How does the angle of release affect the motion of a projectile both vertical and horizontal?
Smaller angles will result in a larger horizontal velocity and smaller vertical velocity. The times of flight will also be shorter since it's closer to the ground. Larger angles have a larger vertical velocity and smaller horizontal velocity. Time of flight will be much longer since it is higher above the ground. As for distance, 45 degrees will result in the greatest distance and for every distance before the furthest one there is an angle above 45 degrees and an angle below 45 degrees that will result in that distance.
What angle has the same horizontal displacment as 20 degrees?
20 degrees is a measure of angular displacement. This cannot be converted to lateral (horizontal) displacement.
