Homework Statement


A small air compressor operates at 1.1 hp electric motor for 5.6 hours a day. How much energy is consumed by the motor daily?


Homework Equations



1hp = 750 watts
power=work/time
work=force*distance

The Attempt at a Solution


1.1hp= 825 watts
5.6 h=20160s
power*time=work
(825w)(20160s)=16632000J I'm confused on what the question is asking for, is it asking for work?

What you've done is correct. A Watt is one joule per second, thus your answer is in joules and is therefore a value for energy. Work is just the change in energy of an object.
