A body of mass `1kg` is suspended from a weightless spring having force constant `600N//m`. Another body of mass `0.5 kg` moving vertically upward hits the suspended body with a velocity of `3.0m//s` and get embedded in it. Find the frequency of oscillations and amplitude of motion.

A

`(pi)/(10)Hz`

B

`(10)/(pi)Hz`

C

`(1)/(2pi)Hz`

D

3.142 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n=(1)/(2pi)sqrt((k)/(m))`
`=(1)/(2pi)sqrt((600)/(1.5))=(1)/(2pi)xx20=(10)/(pi)Hz`
