3.3) The boat was stationary.
As the swimmer dives forwards, the boat moves backwards.
Use the idea of conservation of momentum to explain why the boat moves backwards. [4 marks]
3.4) Explain what would happen to the motion of the boat if there were more people on the boat when the swimmer dived off. [2 marks]
