Answer:
25 N
Explanation:
Force can be found using the following formula.
F=w/d
where w is the work and d is the distance. We know that 100 Joules of work pushes the chair 4 meters. Therefore,
w=100 J
d= 4 m
F=100 J/ 4 m
Divide 100 by 4
100/4=25
F= 25 J/m
1 joule per meter, or J/m is equal to 1 Newton, or N.
F=25 N
The boy uses 25 Newtons of force.
