A particle of mass `0.1kg` moving at an initial speed `v` collides with another particle of same mass kept initially at rest. If the total energy becomes `0.2J` after the collision, what would be the minimum and maximum values of `v`?

`therefore KE = 1/2 (2m) ((v ^(2))/( 4)) ,i.e., (0.2) =1/2 (0.2) ((v ^(2))/( 4)) implies v = 2 sqrt2 m//s`
In case of perfectly elastic collision, first particle stops and the second acquires the same velocity v
`KE =1/2 mv ^(2)i.e., 0.2 =1/2 (0.1) v ^(2) implies v =2 m//s`
Therefore, minimum values of v is 2m/s in casew of perfectly elastic collision and maximum vlaue of v is `2 sqrt2` m/s in case of perfectly inelastic collision.
