Question

A stationary but moveable 450-kg cannon is fired and the 12-kg cannonball moves off to the right with a velocity of 20.0 m/s. What is the connon's velocity (both magnitude and direction) due to the kickback from the firing?

Answer 1

Masscannon*veloctiycannon+massbullet*velocity bullet=0 Momentum is conserved


cannons velocity= (1/masscannon)(-massbullet*velocitybullet)

Answer 2

10 m/s
