A body of mass 4 kg is made to oscillate on a spring of force constant 10 N/m. Calculate (i) angular frequency (2) frequency of vibration and (3) time period of vibration.

Text Solution

Verified by Experts

The correct Answer is:
`1.58 "rad s"^(-1), 0.252//s, 3.97 second`
`omega= sqrt(k//m) = sqrt(10//4) = 15.8 rad s^(-1) , n = omega//2pi = 0.252 s^(-1) T = 1//n = 3.97 ` second
