Question

If a ball with an original velocity of zero is dropped from a tall structure and takes 7 seconds to hit the ground what volicity does the ball have when it reaches the ground

Answer 1

Gravity pulls things to the ground at 9.8 meters per second squared. So to figure this out just do 9.8 times the number of seconds. 9.8 times 7 is 68.6, so the ball would be falling at 98.6 meters per second by the time it reaches the ground.
