A ball hits a vertical wall horizontal at 10 m/s bounces back at 10 m/s

A

there is no acceleration because `10m//s-10m//s = 0 `

B

there may be an acceleration because its initial direction is horizontal

C

there is an acceleration because there is a momentum change

D

even though there is no change in momentum there is a change in direction. Hence, it has an acceleration

A ball hits a wall horizontally at 6.0 m s^(-1) . It rebounds horzontally at 4.4 m s^(-1) . The ball is in contact with the wall for 0.040 s. What is the acceleration of the ball ?

A ball is projected from ground with a speed 70m//s at an angle 45^(@) with the vertical so that it strikes a vertical wall at horizontal distance (490)/(3)m from the point of projection.
