What will be period of pendulum for an observer moving at the speed of 0.95 C with respect to the pendulum?

The period of a pendulum for an observer in motion will be dilated due to time dilation effects at relativistic speeds. The formula for time dilation is T' = T / γ, where T' is the dilated period, T is the proper period, and γ is the Lorentz factor equal to (1 - v^2/c^2)^0.5 with v as the observer's speed and c as the speed of light. Substituting v = 0.95c into the formula and solving will give the dilated period of the pendulum for the observer moving at 0.95c.
