A bomb of mass 9 kg explodes into two pieces of mass 3 kg and 6 kg. The velocity of mass 3 kg is 16 m/s, The kinetic energy of mass 6 kg is

A

192 J

B

162 J

C

150 J

D

200 J

Text Solution

Verified by Experts

The correct Answer is:
A
By conservation of linear momentum,
` 0= 3 xx 16 - 6 xx v`
`therefore v = 8 m//s ` for kg
`therefore` kinetic energy of 6 kg mass `= (1)/(2) xx 6 xx 8^(2)` = 192 J
