2. In the diagram assume the pulley is frictionless and massless. The box hanging from the string is m2. a) If the incline is frictionless determine the value of 0 that will cause the box (mass mi) to accelerate up the ramp -slide up the ramp at constant speed b) Derive a value for u that if the angle of the is such that mi slides up the ramp at constant speed.
