Question

A pendulum is constructed by attaching a 4m rope to a bowling ball. It is then displaced 2m to one side and released.

Answer 1

Answer:

T = 4.0 s

Step-by-step explanation:

The period of a simple pendulum is given by

$period = 2\pi \sqrt{ \frac{l}{g} }$

where l = length of the pendulum

= 4 m

g = acceleration due to gravity

= 9.8 m/s^2

$period = 2\pi \sqrt{ \frac{(4 \: m)}{(9.8 \: \frac{m}{ {s}^{2} } )} } = 4.0 \: s$
