Question

A body thrown in the vertically upward direction rises upto a height „h‟ and comes back to the position of its start. Calculate (a) the total distance travelled by the body and (b) the displacement of the body.

Answer 1

When a body is thrown at a height of H and comes back, the total height calculated is as follows:

a)Distance traveled while rising to height= H On return journey, the total distance traveled = H+H=2H

b)As far as the displacement of the body is concerned it is zero because at the end of the throw, the ball returns in the same position.

Answer 2

Explanation:

The total distance is H+H =2H because the object is going upwards and covers H height and comes back to downward direction and covers H height

The displacement is 0 because object is coming Back to its original point
