A physics professor in a lab releases a 1.44-m long simple pendulum (with a 590 g mass attached) at an angle of 15° to the vertical. Assuming that the pendulum undergoes simple harmonic motion: (a) what is the frequency of the pendulum’s oscillations? (b) What is the pendulum bob’s speed at the lowest point of its motion?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
