MULTI UNIT QUESTION
1. Anthony (71 kg) does a sliding dive in a volleyball game. He starts the slide at a speed of 30 km/h ana skids
to a stop as he saves the ball from hitting the floor. The coefficient of sliding friction between Anthony and the
gym floor is 0.58
a) Calculate the work done by friction to stop Anthony using two different methods
b) Explain why the work done by friction is negative for both methods.
c) Explain how this scenario obeys the law of conservation of energy, including all types of energies
involved and any assumptions required
