Two boxes are connected by by a massless string over a massless, frictionless pulley. Box 1 has a mass

Question

of m1 = 15.0 kg and is initially at rest at the bottom of a frictionless surface inclined at an angle
θ = 30.0◦ above the horizontal. Box 2 has a mass of m2 = 10.0 kg and is initially at a height of 1.50
m above the bottom of the incline.
(a) What is the speed of box 2 when it hits the ground?
(b) What is the average power delivered to the system as box 2
