2. A block of mass m on a horizontal surface is attached to the end of a massless spring with stiffness constant k. The other end of the spring is fixed. The mass is given an initial displacement xo from equilibrium, and an initial speed vo as illustrated in the figure. The gravitational acceleration is g. Ignore friction. (a) (9 Pts.) Find its maximum speed during its motion in terms of the given quantities. (b) (9 Pts.) Find its maximum stretch from equilibrium in terms of the given quantities. k 000000000 m Now assume that there is friction between the block and the horizontal surface, and that the coefficient of kinetic friction is (c) (7 Pts.) What is the total distance traveled by the block if it comes to rest at the equilibrium position of the spring?
