A rock falls off the edge of a cliff and strikes the ground after 3.8 s. What is the height of the cliff? Assume air resistance is negligible
Answered by Jai
Use the formula:
h = vo*t - (1/2)gt^2

Since the rock experiences freefall, initial velocity (vo) is zero:
h = -(1/2)gt^2

Substitute:
h = -(1/2)(-9.8)(3.8^2)
h = ?
