A revolutionary war cannon, with a mass of
2170 kg, fires a 18.1 kg ball horizontally. The
cannonball has a speed of 146 m/s after it has
left the barrel. The cannon carriage is on a
flat platform and is free to roll horizontally.
What is the speed of the cannon immedi
ately after it was fired?
Answer in units of m/s.
