Question

One horsepower is a unit of power equal to 746W. How much energy can a 150-horsepower engine transform in 10.0 seconds?

Answer 1

1,119,000 basically 746 times 150 then multiply that answer by 10 and bam

Answer 2

1 watt = 1 joule/second

1 horsepower = 746 watts = 746 joule/second

(150 horsepower) x (746 watt/HP) x (1 joule/sec / watt) x (10 sec)

= (150 x 746 x 1 x 10) joule = 1,119,000 joules .
