Question
Assume that there is no friction between m2 and the incline, that m2 = 2.4 kg, m1 = 1.2 kg, the radius of the pulley is 0.10 m, the moment of inertia of the pulley is 4.8 kg m2, and θ = 25.0°.
a) Find the combined mechanical energy of both masses the instant the masses are released.
b) What is the new gravitational potential energy of m2 once it moves 1.2 m up the incline?
c) What is the overall mechanical energy of the system once m2 moves 1.2 m up the incline?
d) What is the speed of the masses at that position?
