A couple of boxes with different masses, 4.10 kg and 3.00 kg , hang 0.600 m above the floor from the ends of a cord 5.80 m long passing over a frictionless pulley. The boxes are released from rest with the heavy box falling and lifting up the light box. Find the maximum height above the floor reached by the 3.00 kg box.
Two masses are connected by a light string passing over a light frictionless pulley. The 5.00 kg mass is released from rest at a height of h = 4.00 m above the horizontal floor below. (a) Using the law of conservation of energy, determine the speed of the 3.00 kg mass just as the 5.00 kg mass hits the ground. (b) Use one of the sense-making techniques to analyze your solution to part (a). Clearly state which technique you’re using...
