Calculate the power in horsepower (hp) if 2984 J of work is done in 1 s.

Power is defined as the rate at which work is done.

$$P = \frac{W}{t}$$

Given:
Work ($W$) = $2984 \text{ J}$
Time ($t$) = $1 \text{ s}$

Substitute the values into the formula:

$$P = \frac{2984 \text{ J}}{1 \text{ s}}$$ $$P = 2984 \text{ W}$$

The conversion factor is $1 \text{ hp} = 746 \text{ W}$.
To convert Watts to horsepower, divide the power in Watts by $746 \text{ W/hp}$.

$$P_{\text{hp}} = \frac{P_{\text{W}}}{746 \text{ W/hp}}$$ $$P_{\text{hp}} = \frac{2984 \text{ W}}{746 \text{ W/hp}}$$ $$P_{\text{hp}} = 4 \text{ hp}$$

The power is $\text{4hp}$.
