1. A mass 0.15 kg is attached to a horizontal spring with spring constant k = 100 N/m moves on a horizontal surface. At the initial moment in time, the mass is moving to the right at rate of 3.5 m/s and displacement of 0.2 m to the right of equilibrium.

a) What is the angular frequency, period of oscillation, and phase constant?

b) What is the amplitude of oscillation (Hint: Use energy.) and maximum speed of the spring-mass system?
