A particle of mass 40 g executes a simple harmonic motion of amplitude 2.0 cm. If the time period is 0.20 s, find the total mechanical energy of the system.

Text Solution

Verified by Experts

The total mechanical energy of the system is
`E=1/2momega^2A^2`
`=1/2m((2pi)/T)^2A^2=(2pi^2mA^2)/T^2`
`=(2pi^2(40xx10^-3kg)(2.0xx10^-2m)^2)/(0.20s)`
`=7.9xx10^-3J`.
