A basketball rolls off a deck that is 3. 2 m from the pavement. The basketball lands 0. 75 m from the edge of the deck. How fast was the basketball rolling?.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
