Question

A) A particle with a mass of 4.2 × 10-20 kg is oscillating with simple harmonic motion with a period of 4.3 × 10-5 s and a maximum speed of 3.2 × 103 m/s. Calculate (a) the angular frequency and (b) the maximum displacement of the particle.

B) At a certain harbor, the tides cause the ocean surface to rise and fall a distance d (from highest level to lowest level) in simple harmonic motion, with a period of 11.5 h. How long (in hours) does it take for the water to fall a distance 0.250d from its highest level?

Explanation / Answer

You must look at your equations for torque due to the rotating motion of the problem.
