The kinetic energy of a particle executing S.H.M. is 16 J when it is at its mean position. If the mass of the particle is 0.32 kg , then what is the maximum velocity of the particle

Options

A. 5 m/s
B. 15 m/s
C. 10 m/s
D. 20 m/s

Answer

C

Explanation

`KE=(1)/(2)mv^(2)`
`therefore v^(2)=(2KE)/(m)=(2xx16)/(0.32)`
`v^(2)=100`
`v=100m//s`
