Question

A pendulum has a mass of 3kg and is lifted to a height of .3m. What is the maximum speed of the pendulum

Answer 1

Given data

*The given mass of the pendulum is m = 3 kg

*The given height is h = 0.3 m

The formula for the maximum speed of the pendulum is given as

`v_(\max )=\sqrt[]{2gh}`

*Here g is the acceleration due to the gravity

Substitute the values in the above expression as

`\begin{gathered} v_(\max )=\sqrt[]{2*9.8*0.3} \\ =2.42\text{ m/s} \end{gathered}`

Hence, the maximum speed of the pendulum is 2.42 m/s
