A 0.287-kg particle undergoes simple harmonic motion along the horizontal x-axis between the points x1= -0.269 m and x2= 0.473 m. The period of oscillation is 0.583 s. Find the frequency, f, the equilibrium position, Xeq, the amplitude A, the maximum speed, Vmax, the maximum magnitude of acceleration, amax, the force constant, k, and the total mechanical energy, Etot.
A cable is used to raise a 29kg urn from an underwater archeological site. There is a 21 N drag force from the water as the urn is raised at a constant speed.
