Question
B. Ball Game (Practice Activity – answer key below)
1. A neophyte player catches a 125 g ball moving at 25.0 m/s in 0.02 s. A
professional player catches the same ball in 1.0 s by slightly retracting his
hand during the catch. Find the forces exerted by the ball on the hands of the
two players.
2. Two balls A and B are approaching each other with velocities 4.5 m/s, right
and 7.2 m/s, left, respectively. The mass of ball A is 3.2 kg, while that of ball
B is 5.6 kg. Find the velocity of the two bodies after impact, assuming that
the collision is perfectly inelastic.
