Answer to Question #76302 in Mechanics | Relativity for Sudipta Hazra

Question

a stone thrown from the ground just crosses a Wall of 5 metre in 2 second if the wall is at horizontal distance 25 m from the point of projection of the stone find at what distance the stone Falls behind the wall

Answer 1

We will consider that a wall is the highest point a stone reaches as nothing else is told. According to the symmetry of stone’s movement with respect to a wall the distance from point of projection to the wall is equal to the distance from the wall to the end-point. So stone will fall 25 meters behind the wall.
