Question
A stone is projected from a horizontal plane. It attains maximum height 'H' & strikes a stationary smooth wall & falls on the ground vertically below the maximum height. Assume the collision to be elastic the height of the point on the wall where ball will strike is:
- H/2
- H/4
- 3H/4
- none of these
The correct answer is: 3H/4
Because horizontal velocity is constant so
