Q1. Two balls are rolled off a tabletop that is 0.88 m above the floor. Ball A has a horizontal velocity of 5.0 m/s and that of ball B is 8.0 m/s.

(a) how long does it take each ball to reach the floor after it rolls off edge?

(b) How far does each ball travel horizontally before hitting floor?

Q2. An airplane must reach a speed of 172 mi/h to take off. If the runway is 470 m long, what is the minimum value of the acceleration that would allow the airplane to take off productively?
