A mass of 5 kilogram is resting on a frictionless ramp. It is connected to a cable that passes over a pulley of radius 2 centimeter which is then attached to a second hanging mass. The system is moving at a fix velocity.
A) Evaluate the mass of the hanging block.
B) If the blocks move at 1.5 meter in 3 sec, determine what is the angular velocity of the pulley?
