To find out how much work the engine did, we can use the relationship between power, work, and time. The formula relating these quantities is:
\[ \text{Power} = \frac{\text{Work}}{\text{Time}} \]
Rearranging the formula to solve for work gives us:
\[ \text{Work} = \text{Power} \times \text{Time} \]
We know the following values:
- Power = 190,000 W (or 190 kW)
- Time = 9 s
Now we can substitute these values into the equation:
\[ \text{Work} = 190,000 , \text{W} \times 9 , \text{s} \]
Calculating this gives:
\[ \text{Work} = 1,710,000 , \text{J} \]
Therefore, the engine did 1,710,000 Joules of work.
