Questions  

A mass m oscillates with simple harmonic motion with frequency f=ω2π  and amplitude A on a spring with constant K , therefore

a
The total energy of the system is  12KA2
b
The frequency is  12πKM
c
The maximum velocity occurs, when x = 0
d
All the above are correct

detailed solution

Correct option is D

Total energy is given by 12KA2. time period and frequency are T=2πMK  and  f=12πKMVelocity is max at mean position (x=0) and min (x=A)
