Homework Statement
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.
