By analogy what happens to the level of the lake of uniform depth if the cannonball is thrown into the lake? Do a calculation based on the 25 kg steel ball and a lake that is 10 m in diameter & is of uniform depth. Do you need to account for the mass of the boat? If so, make an assumption on the mass of the boat. Could you easily measure the change in depth of the lake if there was a change in depth?
