A 16 kg canoe moving to the left at 12m/s collides with a 4 kg raft moving to the right at 6m/s. After the collision, the raft moves to the left at 22.7m/s. What is the velocity of the canoe after the collision? You can ignore any external forces from the water

Answer 1

Lord, ignoring friction in water, what a ridiculous reach. Water friction is the number one consumer of power when motoring a boat.

initial momentum=final momentum
Let Right be +, Left be -

16*(-12)+4(6)=4(-22.7)+16(V)
solve for V

Answer 2

-4.825
