Question
A simple pendulum is released from rest when the mass is 33.1 cm above its lowest point. What is the speed of the suspended mass at the bottom of its swing? g= 9.80 m/s2 and ignore air restistance. No mass was given.
Expert Solution
Step 1
Given data
The height from which the simple pendulum is released is calculated as hr = 33.1 cm.
The gravitational acceleration of the g = 9.8 m/s2.
Initially, the body is at rest, therefore, vi = 0
The velocity of the pendulum is calculated by the conservation of energy as,
Here, hr is the released height, hb is the bottom height.
