An object undergoing simple harmonic motion takes 0.13 s to travel from one point of zero velocity to the next such point. The distance between those points is 41 cm. Calculate (a) the period, (b) the frequency, and (c) the amplitude of the motion.

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
