Show that the motion of a helical spring with a small mass attached to its end is simple harmonic. If this system has the same period of oscillation as the simple pendulum in (A) above, find its angular speed and show that the displacement can be written down as = sin , where is the angular displacement, and obtain similar expressions for the velocity and acceleration.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
