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 his then attached to a second hanging mass. The system is moving at a fix velocity.
a) Determine the mass of the hanging box?
b) It the box move 1.5 meter in 3 second, determine what is the angular velocity of the pulley?
