Question

In a pinball machine, a ball launches horizontally as a compressed spring expands 0.06 m. The ball then slides up the face of the playing board, which is 0.50 m long and 0.20 m high. The ball weighs 0.08 kg. The final state for part a) is shown above. a) What is the initial speed of the ball? b) What is the spring constant of the spring? c) Now we'll assume there's friction as the ball returns to the spring. If it slides back down, compresses the spring, and then rebounds to a height of only 10 cm (a total distance of 0.75 m traveled along the face of the playing board), how much work does friction do, assuming no losses in the spring? d) What is the frictional force?
