A block of mass 0.50 kg is moving with a speed of 2.00 m/s on a smooth surface. It strikes another mass of 1.00 kg and then they move together as a single body. The energy loss during the collision is

A

0.16

B

1.00J

C

0.67 J

D

0.34 J

Text Solution

Verified by Experts

The correct Answer is:
C
`m_(1)4_(1)+m_(2)4_(2)=(m_(1)+m_(2))VimpliesV=2/3ms^(-1)`
Energy loss `=1/2=0.5xx2^(2)-1/2xx1.5xx(2/3)^(2)=0.67J`
