A man performed 500 j of work moving a couch in his living room

Sergio039 [100]

Incomplete question. Missing part:

"it took him 10 seconds to move the couch. What was his power?"

Answer:

50 W

Explanation:

The power developed is given by:

$P=\frac{W}{t}$

where

W is the work done

t is the time taken

In this problem,

W = 500 J

t = 10.0 s

Substituting into the equation, we find

$P=\frac{500}{10}=50 W$
