Question

An 8.00-meter box is slid across the floor of a warehouse. What is the magnitude of the force required to do 656 joules of work on the box?

Answer 1

Answer:

F = 82 N

Explanation:

given,

length of the slide, L = 8 m

Work done to slide the box = 656 J

Force required = ?

We know,          

Work done is equal to multiplication of force into displacement.

W = F . s

656 = F x 8        

$F =\dfrac{656}{8}$

F = 82 N              

hence, 82 N of force should be applied to move the box 8 m.
