A 15.0 kg block is attached to a very light horizontal spring of force constant 425 N/m and is resting on a smooth horizontal table (Figure 1). Suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left. Find the maximum distance that the block will compress the spring after the collision. (Hint: Break this problem into two parts - the collision and the behavior after the collision - and apply the appropriate conservation law to each part.)
A block of mass ?=5.4kgm=5.4kg slides on a rough surface and moves toward a spring with a spring constant ?=1474N/mk=1474N/m, as shown in the figure below. When the block is ?=21.4md=21.4m away from the spring, it has a velocity of ?=15.9m/sv=15.9m/s. When the block momentarily stops, it has compressed the spring by ?=29cmx=29cm. What is the coefficient of kinetic friction between the block and the surface below? Provide your answer with two decimal places. Take ?=9.80m/s2g=9.80m/s2.
