A canon of mass 150 kg shot a cannon ball of 1.5 kg which goes with a velocity of 60 m/s. the cannon will recoil with a speed of

A

10.5 m/s

B

6 m/s

C

0.6 m/s

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
From law of conservation of momentum,
`150xxu+1.5xx60=0`
`implies 150u+90=0`
`u=(-90)/(150)=-0.6m//s`
Negative sign shows the opposite direction of motion of cannon from that of cannon ball.s motion of direction.
