Question

## A heavy stone is thrown from a cliff of height h in a given direction. The speed with which it hits the ground (air resistance may be neglected).

**A**

## Must depend on the speed of projection

**B**

## Must be larger than the speed of projection

**C**

## Must be independent of the speed of projection

**D**

## (a) and (b) both are correct

Medium Open in App Solution Verified by Toppr

Correct option is D)

## The speed with which it hits the ground must depend upon the speed of projection and shall always be larger than the speed of projection, because here the potential energy of body shall be converted into kinetic energy.

A heavy stone is thrown from a cliff of height h in a given direction. The speed with which it hits the ground

(A) must be larger than the speed of projection

(B) must be independent of the speed of projection

(C) must depend on the speed of projection

(D)may be smaller than the speed of projection

### Best Answer

Ans-(A) must be larger than the speed of projection

(C) must depend on the speed of projection

The speed with which it hits the ground must depend upon the speed of projnection and shall always be larger than the speed of projection, because potential energy of the body shall be converted into kinetic energy.
