By definition, the work is given by:
[tex]W=F\cdot d\text{.}[/tex]Where W is the work in Joules (J), F is the force in Newtons (N) and d is the distance in meters (m).
In this problem we have:
• W = 280J,
,• d = 35m.
We can find the force F in terms of W and d:
[tex]F=\frac{W}{d}\text{.}[/tex]Replacing the values of W and d, we find that the force F is:
[tex]F=\frac{280J}{35m}=8\frac{J}{m}=8N\text{.}[/tex]In the last step, we used that J = N m.
Answer: The force is F = 8N.
