Hi,

This is how u go about with the problem:

First calculate the vertical velocity of the stone using
v = & radic ;(2*g*h) and then calculate the time taken t for the ball to reach the ground vertically, then using the horizontal velocity that is given to be = 14m/s by using t = 75.7/vand then calculate the horizontal distance travelled by the stone using 14 * t. This the distance travelled by the stone away from the base of the cliff.
