A bomb of mass 12kg explodes into two pieces of masses 4 kg and 8 kg.

1.	A bomb of mass 12kg explodes into two pieces of masses 4 kg and 8 kg. The velocity of 8 kg mass is 6m/s. The kinetic energy of other mass is
Answer» USING conservation of momentum We get 0=MV+ mv MV= -mv 8x6 = -4 x v Thus v= -12m/s Then KE =mv^2/2 KE = 4* (12)^2 /2 Then KE = 144*2 Thus KE = 288J

Answer»

USING conservation of momentum

We get

0=MV+ mv

MV= -mv

8x6 = -4 x v

Thus v= -12m/s

Then KE =mv^2/2

KE = 4* (12)^2 /2

Then KE = 144*2

Thus KE = 288J
