A mass of 0.5 kg moving with a speed of ...

A mass of `0.5 kg` moving with a speed of `1.5 m//s` on a horizontal smooth surface, collides with a nearly weightless spring of force constant `k =50 N//m` The maximum compression of the spring would be.

A

0.15 m

B

0.12 m

C

1.5 m

D

0.5 m

Text Solution

Verified by Experts

The correct Answer is:
A
`1/2 mv^2 =1/2 kx^2`
`x= vsqrt(m/k) = 1.5 sqrt((0.5)/(50))= 0.15 m`
