You push a 4.3 kg block against a horizontal spring, compressing the spring by 16 cm. Then you release the block, and the spring sends it sliding across a tabletop. It stops 69 cm from where you released it. The spring constant is 120 N/m. What is the coefficient of kinetic friction between the block and the table?

    You push a 2.5 kg block against a spring, compressing the spring by 35 cm. Then you release the block, and the spring sends it sliding up the inclined plane. The spring constant is. k = 197 N/m and the coefficient of kinetic friction is, mu_k = 0.31, theta = 38 degree. How far along the incline does the block slide from the compressed position when it is released?

    A 12-kg block is pressed against a spring (spring constant 620 N/mN/m ), compressing it some distance. The block is released from rest and slides across a track as shown in (Figure 1). While most of the track is frictionless, there is a 55-cm section of track that has a coefficient of friction with the block of 0.3. A bit further on, the track ascends into a hill that is 40-cm tall. Part A: What is the minimum compression of...
