A ball is thrown straight up from the top of 128 foot building with an initial speed of 32 feet per second. How long will it take for the ball the hit the ground? How high will the ball be after 3 seconds?

Answer :

The ball drops 32 ft per second
So.... 32 x 3 = 96 ft
So.... 128 ft - 96 ft = 32 ft in 3 sec
So .... 128 ft /32 ft = 4 seconds to hit the ground
