1. The problem statement, all variables and given/known data A particular engine has a power output of 6.00 kW and an efficiency of 26.0%. Assume the engine expels 6000 J of energy in each cycle. (a) Find the energy absorbed in each cycle. (b) Find the time required to complete each cycle. P=W/delta t e=W/Q 1kW=3.6x10^6J Because the engine is expelling 6000J, does this mean it is negative? I'm not quite sure how to approach this problem.
