Question

An osillating pendulum as maximum kinetic energy at .... and maximum potential at .....

A)

extreme postion and mean position

B)

at mean position both KE and PE are maximum

C)

at extreme position both are maximum

D)

at mean and extreme postion 

​

Answer 1

Answer is D
Particle speed increase from extreme to mean position so kinetic energy increases
But speed decreases from mean to extreme position so kinetic energy decreases so potential energy increases
