Question

If you perform 10 joules of work lifting a 10-N box from the floor to a shelf, how high is the shelf?

A. 1 m
B. 2 m
C. 10 m
D. 100 m

Answer 1

Joule = newton * Meter
10 = 10* (???)

Answer 2

I have no clue. I don't understand how to even begin doing this problem.

Answer 3

Any way you could help me here?

Answer 4

Work = Force * Displacement

Answer 5

W = F*d

10 = 10*d

solve for d

Answer 6

So D is 1?

Answer 7

The work done \(W\) in joules against gravity, equals the weight force \(F\)in newtons time the vertical displacement \(y\) in meters (lifting something up takes positive work)
\[W=Fy\]

Answer 8

correct, displacement is 1 meter

Answer 9

since d = 1

Answer 10

Okay.
Thank you so much. (:
