A) at position 1
B) at position 2
C) the first time at position 3
D) the last time at position 3
Correct Answer: C
Solution :
The pendulum has the most kinetic energy at position 3, as all the gravitational potential energy is converted to kinetic energy. It has the most kinetic energy the first time at position 3, as some energy is lost to the surroundings (as seen by the decreasing amplitude of oscillation). Thus the overall energy possessed by the pendulum decreases over time.You need to login to perform this action.
