A lawnmower engine running for 20 min does 4560000 j of work. What is the power output of the engine? (Power: P = W/t)
A:3800 W
B:228,000 W
C:91,200,000 W
D:547,200,000 W

Respuesta :

Answer:

Power output, P = 3800 watts

Explanation:

It is given that,

Work done by the lawnmover engine, W = 4560000 J

Time taken, t = 20 min = 1200 sec

We have to find the power output of the engine. Power of an engine is given by work done per unit time taken i.e.

[tex]P=\dfrac{W}{t}[/tex]

[tex]P=\dfrac{4560000\ J}{1200\ s}[/tex]

P = 3800 Watts

Hence, the power output of the engine is 3800 watts.
