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

What is acceleration?

A truck starts from rest and accelerates* uniformly at 2.0ms*2. At f = 10 s, a stone is dropped by a person standing on the top of the truck (6 m high from the ground). What are the (a) velocity, and (b) acceleration of the stone at f = 11 s? (Neglect air resistance:)

A player throws a bail upwards with an initial speed of 29.4 m s^-1 . What are the velocity and acceleration of the ball at the highest point of its motion?

A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate the total time it takes to return to the surface of the earth.

A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate the maximum height to which it rises.

A cricket ball is vertically thrown up with a velocity 20 m/s. If the acceleration' - in the opposite direction is 10 m//s^2 , how high will the ball rise? What time will it take to reach the maximum height?

A ball is thrown vertically upwards with a velocity 4.9 m/s from the floor of a bridge over water. The ball strikes water after 2 seconds. Calculate the height of the bridge.

What is the angle between velocity and acceleration vector in a circular motion?

A railway carriage moves over a straight level track with an acceleration 'a'. A passenger in carriage drops a stone. What is the acceleration of the stone with respect to carriage and the earth?

A ball is thrown up with a velocity 4.9ms^-1 . Find the maximum height reached by the ball. How long does it spend in air?
