. A block of mass 2.00 kg is attached to a horizontal spring with a force constant of 500 N/m. The spring is stretched 5.00 cm from its equilibrium position and released from rest. Use conservation of mechanical energy to determine the speed of the block as it returns to equilibrium

(a) if the surface is frictionless

(b) if the coefficient of kinetic friction between the block and the surface is 0.350

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?
