A particle of mass 0.1 kg is subjected to a force which varies with distance as shown in figure.

If it starts its journey from rest at x = 0, its velocity at `x=12` m is

A

0 m/s

B

`20sqrt2` m/s

C

`20sqrt3` m/s

D

40 m/s

Text Solution

Verified by Experts

The correct Answer is:
D
W=area=80 =`1/2(0.1)u^2`-0
so u=40 m/s
