Question

A simple pendulum of length 1m has a bob af mass 100g.It is displaced through angle of 60 degrees from vertical and then released. The K. E of the bob when it passes through the mean position is _ (g= 10 m/s²)
1) 0.25J
2)0.5J
3)1J
4)1.4J

Answer 1

Answer:

A pendulum is a body suspended from a fixed support so that it swings freely back and forth under the influence of gravity. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
