Q. Consider the system with m1 = 24kg, m2 = 14.60kg, R = 0.1400m, and the mass of the pulley M = 5.0kg. Object m2 is resting on the floor, and object m1 is 4.600m above the floor when it is released from rest. The pulley axis is frictionless. The cord is light, does not stretch, and does not slip on pulley.
Q. A spring with k = 55N/m hangs vertically next to a ruler. The end of the spring is next to the 15 cm mark on the ruler. If a 2.10kg mass is now attached to the end of spring, where will the end of the spring line up with the ruler marks?
