Question

A 133 g ball is tied to a string. It is pulled to an angle of 6.40�� and released to swing as a pendulum. A student with a stopwatch finds that 14 oscillations take 10.5 s. What is the period of the pendulum?

Answer 1

The period of the pendulum is 0.75 seconds.

Step-by-step explanation:

To find the period of a pendulum, we can use the formula:

T = 2π√(L/g)

Where T is the period, L is the length of the string, and g is the acceleration due to gravity. In this case, the period is given as 10.5 seconds for 14 oscillations. So, the period for one oscillation can be calculated by dividing 10.5 seconds by 14, which equals 0.75 seconds per oscillation. Since the period of a pendulum is the time it takes for one complete oscillation, the period of the pendulum is 0.75 seconds.
