Question

A 925-kg car can produce a useful power output of 48.5 hp. What is the car's power output in watts?

A. 34,000 W
B. 33,900 W
C. 34,500 W
D. 35,000 W

Answer 1

The car's power output in watts, calculated by converting 48.5 horsepower to watts (48.5 hp × 746 W/hp), equals 36,197 watts or approximately 36.2 kW. The alternatives do not include the closest response.

Step-by-step explanation:

The car's power output in watts can be calculated by converting the horsepower to watts. Since 1 horsepower is equivalent to 746 watts, you would multiply the car's power output in horsepower by this number to find the power output in watts.

To find the car's power output in watts:
48.5 hp × 746 W/hp = 36,197 W

This result does not exactly match any of the options provided. However, the closest answer from the options given by rounding to the nearest hundred is 36,200 W, which would be approximately 36.2 kW. Since this option is not listed, we must clarify with the student or check for any possible errors in the question or the options provided.
