Q1. An green hoop with mass mh = 2.5 kg and radius Rh = 0.14 m hangs from a string that goes over a blue solid disk pulley with mass md = 2.1 kg and radius Rd = 0.09 m. The other end of the string is attach to a massless axel through the center of an orange sphere on a flat horizontal surface that rolls without slipping and has mass ms = 3.9 kg and radius Rs = 0.22 m. The system is released from rest.

Q2. With what minimum speed should you toss a 140g ball straight up to hit the 11.0m-high roof of the gymnasium if you release the ball 1.30m above the ground? Resolve this problem using energy.
