Question

A student tries to measure the period of a pendulum that is already swinging left and right. At that moment when the pendulum is fully to the left, she counts ‘one’ and starts a stopwatch. She counts successive swings each time the pendulum returns to the left. When she counts ‘ten’ she stops the stopwatch, and sees that it reads 12.0s.
a)What was her mistake?
b)What is the period of swing of the pendulum?
c)In this particular experiment, explain the likely effect of her reaction time on her answer.
