Two objects (m1 = 5.15 kg and m2 = 2.75 kg) are connected by a light string passing over a light, frictionless pulley as in the figure below. The 5.15-kg object is released from rest at a point h = 4.00 m above the table.
(a) Determine the speed of each object when the two pass each other.
(b) Determine the speed of each object at the moment the 5.15-kg object hits the table
(c) How much higher does the 2.75-kg object travel after the 5.15-kg object hits the table?
