- Homework Statement
- A force F=Fx ı +Fy j with Fx =50N and Fy =12N is exerted on a particle as the particle moves along the x axis from x=1.0m to x=-5.0m.

(a) Determine the work done by the force on the particle.

(b) What is the angle be- tween the force and the particle’s displacement?

- Relevant Equations
- W=F*x

Since we don't know how far does it move in y-axis, I assumed that only x-component does work.

a) W=Fx*Δx = 50N*(-6m) = -300 J

b) Θ = arctan(12/50) = 13.5°

But, I'm not sure that did I do this in right way...h
