A bomb of mass `9 kg` explodes into `2` pieces of mass `3 kg` and `6 kg`. The velocity of mass `3 kg is 1.6 m//s`. The `K.E. of mass 6 kg` is

A

3.84 J

B

9.6 J

C

1.92 J

D

2.92 J

Text Solution

Verified by Experts

The correct Answer is:
C

`3 xx1.6 = 6 xx v implies v = 0.8m//s`
`K =1/2 xx 6(0.8)^2 = 3 xx 0.64 =1.92 J`
