A rock is dropped from the top of a building and hits the ground at a velocity of
soldier1979 [14.2K]

The height of the building comes to be 81 feet.

Initial velocity u= 0 feet/sec

Final velocity v= 72 feet/sec

The acceleration due to gravity g =32ft /sec²

Height of the building h= suppose h

<h3>What is the equation of motion?</h3>

The equation of a motion is:

v^{2} =u^{2} +2gh

Where u and v are the initial and final velocities.

72^{2} =0+2*32*h\\144 = 64h\\h=81

So, the height of the building = 81 feet.

Therefore, the height of the building comes to be 81 feet.
