A block of mass 0.50kg is moving with a ...

A block of mass `0.50kg` is moving with a speed of `2.00m//s` on a smooth surface. It strikes another mass of `1 kg` at rest and they move as a single body. The energy loss during the collision is

A

1.00 J

B

0.67 J

C

0.34 J

D

0.16 J

Text Solution

Verified by Experts

The correct Answer is:
B

`P_(i)=p_(f)` (momentum conservation)
`rArr 0.5xx2=1.5xxv`
`rArr v=0.67`
energy loss `=1-(1)/(3)=(2)/(3) =0.67 J`
