Final answer:

A 158 horsepower engine, where one horsepower is equivalent to 746 watts, can transform 353,604 joules of energy in 3 seconds, calculated by multiplying the power output in watts by the time in seconds.

Step-by-step explanation:

The question asks us to calculate the amount of energy that a 158 horsepower engine can transform in 3 seconds.

Since one horsepower is equal to 746 watts (W), and power is the rate at which energy is transformed, we can multiply the engine's power output in watts by the time in seconds to find the energy in joules (since 1 watt = 1 joule per second).

First, we convert the engine's power output from horsepower to watts:

  • 158 hp × 746 W/hp = 117,868 W

Then, we calculate the energy transformed in 3 seconds:

  • 117,868 W × 3 s = 353,604 joules (J)

Therefore, a 158 horsepower engine can transform 353,604 joules of energy in 3 seconds.
