Hello!
We have the following data:
Suppose we treat a constant force (cos 0º = 1)
W (work) = 200 Joules (1N x m)
F (Strength) = 50 N
d (distance) =? (in meters)
We have the following formula of the work of a force:]
[tex]W = F*d*cos \alpha [/tex]
Solving:
[tex]W = F*d*cos \alpha [/tex]
[tex]200 = 50 * d * cos\:0\º[/tex]
[tex] 200 = 50 * d * 1 [/tex]
[tex]200 = 50d[/tex]
[tex]50d = 200[/tex]
[tex]d = \frac{200}{50} [/tex]
[tex]\boxed{\boxed{d = 4\:m}}\end{array}}\qquad\checkmark[/tex]
