Question

The bob of a pendulum is released from a horizontal
If the length of the pendulum is 1.5 m speed with which the bob arrives at the lowermost point. given that it dissipated 5% of its
initial energy against air resistance ?​

Answer 1

Answer:

Thus, speed of the bob at lowermost position will be 5.34 m/s. According to the law of conservation of energy, the total energy of the system remains constant. As the bob moves from the horizontal position to the lowermost point, 5% of its energy gets dissipated
