Question

a body thrown in vertically upward direction reaches a maximum height h , then returns to ground . find the distance travelled and displacement​

Answer 1

As we know that the total length of the journey is the distance,Distance = h+h = 2h

also we know that the shortest gap between the initial and final positions the body is coming back to the initial position the net displacement is zero.

Answer 2

Displacement is 0
Let the height till which the Body went be a
Therefore distance travelled is a +a = 2a
