A ball thrown up, what its velocity and acceleration at the top?

A ball is thrown straight up. What is its velocity and acceleration at the top?

A ball is thrown up with a certain velocity at anangle theta to the horizontal. The kinetic energy KE of the ball varies with horizontal displacements as:

A ball is thrown up with a certain velocity at angle theta to the horizontal. The kinetic energy varies with height h of the particle as:

A ball is thrown upwards with a velocity of 29.4 ms^(-1) in the absence of air resistance. (i) Mention the direction of the acceleration during the upward motion of the ball. (ii) What are the velocity and acceleration of the ball at the highest point? (iii) How much high the ball goes up? (iv) Find the time taken by the ball to reach the ground. Take g = 9.8 ms^(-2)

At the top of the trajectory of a projectile, the directions of its velocity and acceleration are

At the top of the trajectory of a projectile, the directions of its velocity and acceleration are

At the top of the trajectory of a projectile, the directions of its velocity and acceleration are

A body is thrown up in a lift with a velocity u relative to the lift, and returns to the lift in time t . Show that the lift's upward acceleration is (2u-gt)/t

A ball is thrown vertically upward with a velocity u from the top of a tower. If it strikes the ground with velocity 3u, the time taken by the ball to reach the ground is

When a body is thrown up in a lift with a velocity u relative to the lift, the time of flight is found to be t . The acceleration with which the lift is moving up is
