Q2 of 111 Page 250

The time period of a particle in simple harmonic motion is equal to the time between consecutive appearances of the particle at a particular point in its motion. This point is

The time period of the pendulum is defined as the time taken by pendulum to complete one oscillation. When the time period is measured, then it is the time between consecutive appearance of the particle at extreme position.

The force acting on a particle moving along X-axis is F = - k(x - u0 t) where k is a positive constant. An observer moving at a constant velocity u0 along the X-axis looks at the particle. What kind of motion does he find for the particle?

A student says that he had applied a force F = - k√x on a particle and the particle moved in simple harmonic motion. He refuses to tell whether k is a constant or not. Assume that he has worked only with positive x and no other force acted on the particle.
