This question involves the concepts of power and current.

The power output of the motor is "10.08 hp".

<h3>Power Output</h3>

The power output of the motor can be found using the following formula:

P = ηVI

where,

Therefore,

P = (0.9)(38 A)(220 V)

P = 7524 watt

converting this to horsepower:

P = (7524 watt)( $\frac{1\ hp}{746\ watt}$ )

P = 10.08 hp
