Chapter 13 Oscillations About Equilibrium Q.2CQ

A person rides on a Ferris wheel that rotates with constant angular speed If the Sun is
directly overhead. does the person’s shadow on the ground undergo periodic motion? Does it
undergo simple harmonic motion? Explain.

Solution:

The persons shadow undergoes periodic motioni with the same period as the period of the Ferris wheel’s rotation In fact, if we take into account the connection between uniform
circular motion and simple harmonic motion, we can say that the shadow exhibits simple harmonic
motion as it moves back and forth on the ground

of the rocking?

Solution:
