I need help setting up this problem. I need help setting up the equation, knowing what cancels and what doesn't and what values to use. Two objects are connected by a light string passing over a light, frictionless pulley as in Figure P5.63 (see attached file). The 5 kg object is released from rest at a point 4 m above the floor. (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 kg object hits the floor, (c) how much hgiher does the 3 kg object travel after the 5 kg object hits the floor? Any help is appreciated. Thanks.
