Set a weighted 3 kg atop a frictionless incline. When sliding to the bottom with an inclined plane, the toxin weight K = 400 N/m is placed horizontally. Assume that the system loses mass due to friction. a –Find the compression ∆x of the spring –If the horizontal surface of the system is close to k = 0.2, how far will the 10th weight slide before coming to a complete stop?

(8%) problem 12. a bowling ball of mass mb 3 kg 's rolled down the lane with a velocity ofy-2/ m s lt strikes a single remaining pin mp 0.93 kg head on. after the collision the bowling ball has a velocity (in the same direction) of v2 1.1 m/s. = ▲ 33% part (a) write an expression for the velocity of pin in the horizontal direction after the impact, im ,, 33% part (b) what is the pins speed in ms? 33% part (c) assuming the coefficient of friction s μ,-0.1. how far in meters could the pin slide before stopping if it doesn't topple?
