The period of a pendulum is measured to be 3.0 s in the inertial frame of the pendulum find the period by an observer moving at 0.95 C with respect to pendulum
Correct answer: C. 9.6s
- A. 5.6s
- B. 7.9s
- C. 9.6s
- D. 9.8s
Explanation
The time dilation effect from special relativity is given by the equation:T'= T/ √1-v2/c2Where:T' is time observed in the moving frame.T is time measured in the stationary frame.v is relative velocity between the frames.c is the speed of light.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
