A BALL IS DROPPED FROM A HEIGHT OF 70 FT. HOW LONG WILL IT TAKE FOR THE BALL TO HIT THE GROUND?
A freely falling body has an equation H= 1/2 g t^2 H= height t = time

+t+=+sqrt%282H%2Fg%29

plug H =70 ft , g = 32.2ft/s^2

+t+=+sqrt%282%2A70%2F32.2%29
= 2.085 seconds
It will take approximately 2.085 seconds for the ball to hit the ground.
