A spring with spring constant 230 N/m vibrates with an amplitude of 12.0 cm when 0.530 kg hangs from it.(adsbygoogle = window.adsbygoogle || []).push({});

(a) What is the equation describing this motion as a function of time? Assume the mass passes through the equilibrium point, toward positive x (upward), at t = 0.120 s.

The equation is:

(b) At what times will the spring have its maximum and minimum lengths? (Consider only the first instances after t = 0.)

(c) What is the displacement and direction at t = 0?

(d) What is the force and its direction exerted by the spring at t = 0?

(e) What is the maximum speed?

When is it first reached after t = 0?
