A 2.4kg block sliding on a rough horizontal surface is attached to one end of a horizontal spring ( k=188/m) which has its other end fixed. The block passes through the equilibrium position with a speed of 2.76m/s and first comes to rest at a displacement of 0.23m from equilibrium. What is the coefficient of kinetic friction between the block and the horizontal surface?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
