Question

car used 250,000 w of power to complete a race in 12 s, how much work did the car do? 2080 j 20,800 j 300,000 j 3,000,000 j

Explanation:

Step1: Recall power-work relationship

Power $P$ is defined as work $W$ divided by time $t$, so rearrange to solve for work: $W = P \times t$

Step2: Substitute given values

$P = 250000\ \text{W}$, $t = 12\ \text{s}$
$W = 250000 \times 12$

Step3: Calculate the result

$W = 3000000\ \text{J}$

Answer:

3,000,000 J
