a lawnmower engine running for 20 min does 4,560,000 j of work. what is the power output of the engi (power: p = w/t)\n3800 w\n228,000 w\n91,200,000 w\n547,200,000 w

Answer

Explanation:

Step1: Convert time to seconds

$t = 20\times60\ s=1200\ s$

Step2: Calculate power using formula

$P=\frac{W}{t}=\frac{4560000\ J}{1200\ s}=3800\ W$

Answer:

A. 3800 W
