Question

How much work is done if 10 N is applied to a 5kg object for 10 meters if there is an opposing force of 5 N

Answer 1

Answer:

50 J

Explanation:

The net force acting on the box is given by the algebraic sum of the two forces, so:

$F=10 N -5 N = 5 N$

The net work done on the box is equal to (assuming the net force is parallel to the displacement of the object)

$W=Fd$

where

F = 5 N is the net force on the object

d = 10 m is the displacement of the object

Substituting,

$W=(5 N)(10 m)=50 J$
