A linear harmonic oscillator of force constant `2 xx 10^6 N//m` and amplitude (0.01 m) has a total mechanical energy of (160 J). Its.

Options

A. maximum potential energy is `100 J`
B. maximum kinetic energy of `100 J`
C. maximum potential energy is `160 J`
D. minimum potential energy of zero

Answer

B, C

Explanation

`KE_(max)=(1)/(2)kA^(2)=(1)/(2) xx 2xx 10^(6) xx(0.01)^(2)=100 J`
`U_(max) =TE = 160 J`.
