Question

How much work can a 6.0-hpmotor do in 3.0h?

Express your answer to two significant figures and include the appropriate units.

Step 1

The expression for power is,

Step 2

Here, *W* is the work that is done in *t* duration of time.

Rewrite the above expression for work done.

Step 3

Now, 1 horsepower is equivalent to 745.7 W. Substitute ...
