Carlos and Katherine are estimating acceleration by rolling a ball from rest down a ramp. At 1 second, the ball is moving at 5 meters per second m/s, at 2 seconds, the ball is moving at 10 m/s, at 3 seconds, the ball is moving at 15m/s, and at 4 seconds, it is moving at 20m/s. When graphed on an xy-plane, which equation best describes the ball's estimated acceleration where y expresses speed and x ecpresses time?

A body moving with uniform acceleration attains velocity 25m/s after 5 seconds and 34 m/s after 8 second. Calculate the distance it covers in the 10th second.

Ball of mass 5.0 kilograms moving at 20m/s collides with ball B of unknown mass moving at 10m/s in the same direction . After collision ball A moves at 10m/s an ball B at 15m/s , both still in the same direction. What is the mass of ball B?

A 2 kg ball , moving at 10 m//s , collides head - on with a 3 kg ball moving in the opposite direction at 20 m//s . If the coefficient of restitution is 1//3 , then the energy lost in the collision is

A 1 kg ball moving at 12 m//s collides head on with a 2g ball moving in the opposite direction at 24 m//s . The velocity of each ball after the impact, if the coefficient of restitution is 2//3 is

A ball of mass 150g starts moving at 20 m/s^2 and hit by a force which acts on it for 0.1 second. Then the impulsive force is

A highly elastic ball moving at a speed of 3 m//s approaches a wall moving towards it with a speed of 3 m//s . After the collision. the speed of the ball will be
