a horse does 860 j of work in 420 seconds while pulling a wagon. what is the power output of the horse? round your answer to the nearest whole number. the power output of the horse is w.
Answer
Explanation:
Step1: Recall power formula
Power $P=\frac{W}{t}$, where $W$ is work and $t$ is time.
Step2: Substitute values
Given $W = 860\ J$ and $t=420\ s$, so $P=\frac{860}{420}$.
Step3: Calculate and round
$P=\frac{860}{420}\approx2.0476$, rounding to the nearest whole - number gives $P = 2$.
