A Lazy Susan is a rotating disk with a mass of 5.52 kg and a radius of 0.250 you push the edge with a 12.4 N force, tangent to the circle, what is its angular acceleration? m. If [?] rad/s2​

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
