A horizontal spring with spring constant 85 N/mN/m extends outward from a wall just above floor level. A 7.5 kgkg box sliding across a frictionless floor hits the end of the spring and compresses it 3.5 cmcm before the spring expands and shoots the box back out. How fast was the box going when it hit the spring

Agalvanometer has an internal resistance of 100 ω and deflects full-scale at 2.00 ma. what size resistor should be added to the galvanometer to convert it to a milliammeter capable of reading up to 4.00 ma, and how should this resistor be connected to the galvanometer?

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
