A 8.53 kg mass is on a frictionless 30degree ramp. It is attached by a massless string to a 4.83 kg mass suspended vertically. The string attaching the 2 masses passes over a uniform pulley with a radius of .1m & mass of 1kg with constant 9.89 N-m resistive torque? What is the magnitude of the acceleration of the vertically hanging mass, if the rope does not slip on the pulley?
Two masses, 5.95 kg & 3.06 kg, are suspended from a pulley with a radius of 2.12 m and mass of 1.65 kg, that has a constant frictional torque of 6.08 N-m, what is the magnitude of the acceleration of the masses?
