a power = work/time question.
A broken car is being pushed to a garage.
a) work out the drivers output if he takes 1 hour and 45 mins to push his car 2km with a force of 900N.
b) work out the total power output if the driver has to stop for a 30 minute kip halfway.
c) the driver's maximum power output is 500W. how long would it take him to push the car to the garage at maximum output?
