The position of a weight on a spring is s(t) = -5 cos 4nt %3D inches after t seconds. Include units in all of your answers. 1. What is the maximum height the weight will rise above equilibrium? 2. What are the frequency and period? 3. When will the weight reach its first maximum? 4. Use your calculator to estimate s(0.3). Indicate if the weight is above or below equilibrium at this time. Is the weight moving up or down when t = 0.3?
