A4.90 kg object on a horizontal frictionless surface is attached to a spring with spring constant 1030 n/m. the object is displaced from equilibrium 50.0 cm horizontally and given an initial velocity of 10.1 m/s back toward the equilibrium position. (a) what is the frequency of the motion? hz (b) what is the initial potential energy of the block–spring system? j (c) what is the initial kinetic energy? j (d) what is the amplitude of the motion?
