Sierra did 500 j of work to move her couch. if she exerts 250 n of force on the couch, how far did she move it? (work: w = fd)

0.5 m
2 m
250 m
750 m

2 m

Explanation:

The work done by Sierra is given by:

where

W is the work done

F is the force exerted on the couch

d is the distance through which the couch has been moved

In this problem, we know W=500 J and F=250 N; by re-arranging the equation, we can find the distance, d:

Answer : Distance = 2 m

Explanation :

Work done by Sierra, W = 500 J

Force exerted by Sierra, F = 250 N

We have to find the distance covered by the couch.

Using the definition of work done to find the distance.

Where

d is the distance covered by Sierra.

So, the distance covered by her is 2 m.

Hence, the correct option is (b) " 2 m ".
