How do you find vertical and horizontal components when given the initial velocity?
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).
What is the formula of velocity?
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
A train travels from one city to another its initial velocity is lower then its final velocity?
Positive acceleration.
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
What is the value of constant horizontal velocity?
In projectile motion, since , there's no force in the horizontal direction which can change the horizontal motion therefore the horizotal velocity remains conserved Vx=Vox= Vocos theta by using above formula , constant horizontal initial or final velocity can be found. since Initial = final horizontal velocity.
Where A Particle Is Projected Along A Linear Plane. The Horizontal Component Of The Velocity Is Twice The Vertical Component What Is The Initial Magnitude Of The Velocity And The Angle At Which It Is?
The initial velocity is sqrt(5) times the vertical component, and its angle relative to the horizontal direction, is 0.46 radians (26.6 degrees).
How do you find vertical and horizontal components when given the initial velocity?
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).
A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
What is the formula of velocity?

Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
What is the difference bet increasing acceleration and increasing deceleration?
firstly, we should know what is meaning of accelerate i.e(to increase)that means acceleration is something which increases some physical quantity.In mechanics,acceleration means rate of change of velocity per unit time .a=v-u/twhere v=final velocity, u=initial velocity ,t=time& a=accelerationnow ,if the change in velocity is positive then i.e final velocity is greater than initial velocity.Suppose to be positive acceleration or simply acceleration.But when change in velocity is negative then acceleration is negative suppose to bedeceleration.Important thing is that acceleration is vector .so ,positive or negative accelerationindicates direction of acceleration.hence , force ,by Newton's second law.acceleration tends to increase the velocity of a moving body in the direction of motion while deceleration tends to decrease the velocity of the moving body applies in opposite direction of motion upto zero velocity after which it accelerate means increase velocity of the body but in opposite direction of initial direction of motion.
A shell is fired from the ground with an initial velocity of 1600m s at an angle of 64 to the horizontal What is the shells horizontal range?
If a shell is fired from the ground with velocity of 1600 m and an angle of 64 to the horizontal then it would have a horizontal rang of 55.0. This is considered math.
What is the initial direction on the projectile's velocity?
its upward at some specified angle
Which is greater in positive acceleration initial or final velocity?
inital velocity (u) should be less
A train travels from one city to another its initial velocity is lower then its final velocity?
Positive acceleration.
The horizontal and vertical components of the initial velocity of a tennis ball are 18.2 ms and 21.3 ms respectively what is the magnitude of the initial velocity of the ball?
To take the magnitude of the velocity you will need to square both the horizontal and vertical components and then take the square root of their sum. So: V=(Vx2+Vy2)1/2
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
