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 and why it is relevant. (c) Find the maximum height to which the 3.00 kg mass rises after the 5.00 kg mass hits the ground. The image is not drawn to scale, assume that the 3.00 kg box does not hit the ceiling. (d) Use a different sense-making technique than you used in part (b) to analyze your solution to part (c). Clearly state which technique you're using and why it is relevant
