A 28 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 4.8 kN/m. The block is pulled to the right so that the spring is stretched 7.2 cm beyond its relaxed length, and the block is then released from rest. The frictional force between the sliding block and the surface has a magnitude of 37 N. (a) What is the kinetic energy of the block when it has moved 1.6 cm from its point of release? (b) What is the kinetic energy of the block when it first slides back through the point at which the spring is relaxed? (c) What is the maximum kinetic energy attained by the block as it slides from its point of release to the point at which the spring is relaxed?

A 0.019 kg block on a horizontal frictionless surface is attached to a string whose spring/force/elastic constant k is 120 N/m. The block is pulled from its equilibrium position at x=0 m to a displacement x=+0.080 m and is released from rest. The block then executes simple harmonic motion along x-axis (horizontal). When the displacement is x=0.051 m, what is the kinetic energy of the block in J?

You push a 3.2 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 62 cm from where you released it. The spring constant is 170 N/m. What is the coefficient of kinetic friction between the block and the table?
