Question:

The ball was dropped from the roof of a 120-foot building, and it took 45 seconds to hit the ground. At what speed did the ball travel?

A 160 fpm
Explaination

The ball traveled at a speed of 160 fpm. To find the motion of the ball, you will need to use the following formula: average speed = distance traveled / time to travel distance. For this problem, we will convert the seconds to minutes: 45/60 = 0.75 minutes. Then, find the rate of speed: 120 feet / 0.75 minutes = 160 fpm.
