Questions
A ball hits a vertical wall horizontally at 10 m/s bounces back at 10 m/s
detailed solution
Correct option is C
As the ball bounces back with same speed so change in momentum = 2 mv and we know that force = rate of change of momentum i.e., force will act on the ball so there is an acceleration.Similar Questions
A ball is projected vertically down with an initial velocity from a height of 20 m onto a horizontal floor. During the impact it loses 50% of its energy and rebounds to the same height. The initial velocity of its projection is (in m/s) [Take g = 10 m/s2]
