A200 g ball is tied to a string. it is pulled to an angle of 8.0° and released to swing as a pendulum. a student with a stopwatch finds that 10 oscillations take 12 s. how long is the string?

Explanation:

Period of simple is given by the equation

It will not depend upon angle and mass of ball.

A student with a stopwatch finds that 10 oscillations take 12 s.

So we can find period for 1 oscillation

Substituting in equation of period

The string is 0.36 m long.

The string is 36 cm long.

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
