A ball rolls off a table 4ft high while moving at a constant speed of 5ft/s.
a) How long does it take for the ball to hit the floor after it leaves the table?
b) At what speed does the ball hit the floor?
c) If a ball were dropped from rest at table height just as the rolling ball leaves the table, which ball would hit the ground first? Justify your answer.
How should I solve this question? Thank you very much!
