Momentum Problem

  • #1
You load a 100 kg cannon with a 10kg cannonball. Initially the cannon is at rest. You fire the cannonball at a velocity of 150m/s.

Momentum = mass*velocity

Im having trouble coming up with the parts of the scenario, or splitting this story into pieces to solve this problem using: (Vm1(initial)+vm2(initial) = vm1(final) + vm2(final).

Any help and tips appreciated.

Initially nothing is moving, so the whole left side is zero.
Put your numbers in the right side.

initial momentum is zero. so final also has to be zero.
here you CANNOT use conservation of energy
