Question

You hang a 175 g mass on a spring and start it oscillating with an amplitude of 7 cm and a phase constant of −π/3.

a. If the spring stretched 16 cm when you first hang the mass on it, how long will one oscillation take?

b. Draw a position vs. time graph for two cycles of motion. Consider the position y = 0 to be the equilibrium position of the mass hanging on the spring.

c. Will the velocity be (positive or negative) and (increasing or decreasing or at a turning point) at t = 0.5s?

d. Will the acceleration be (positive or negative) and (increasing or decreasing or at a turning point) at t = 0.5s?

e. Will the force be (positive or negative) and (increasing or decreasing or at a turning point) at t = 0.5s?
