A stone was dropped off a cliff and hit the ground with a speed of 160 ft/s. What is the height of the cliff?
Take the free fall acceleration to be 32ft/s^2
h= _______ft?
vfinal^2= 2gh you are given g, and vfinal.
A stone was dropped off a cliff and hit the ground with a speed of 160 ft/s. What is the height of the cliff?
Take the free fall acceleration to be 32ft/s^2
From Vf^2 = Vo^2 + 2gh,
160^2 = 0 + 2(32)h > h = 20 feet.
