1. A 75.0 g toy is bouncing on the end of a 325 N/m horizontal spring. At t = 0, the toy is 0.0120 m right of its equilibrium position and it has a velocity of 0.425 m/s to the left. (a) What is the total energy of the system? (b) What is the amplitude of the toy's motion? (c) What is the maximum speed of the toy's motion? (d) What is the phase shift of the toy's motion, assuming a cosine function? How would the answer change if the toy was going right?
