A science student drops a rok down a mine shaft. It takes 3 sec. for the rock to hit the bottom of the shaft , at what speed of the rock just before impact?
32 feet per second per second is the acceleration rate of earth. At the end of second 1 the speed is 32 feet per second, at the end of second 2 it is 64f.p.s., At the and of second 3, 96f.p.s. minus atmospheric drag. Ask your teacher about Terminal Velocity.
