Question

2. Determine the work done by force F along the path C, that is, compute the line integral SF. dr from point A to point B. You need to find the parameterization of the curve C с and use it to find the line integral: Work = [F-di =[F(F(t).F"(t)dt Use F = (-yx) { +(x²) j in Newtons. and use a = 3 meters in the figure. Parameterization of a circle: Remember that for a circle: r(t) = [rcos(t) rsin(t) 0); ___sts rad Is the curl of F equal to a zero vector? Calculate it. С A Is the work of F path independent? Why? Find F(r(t)) and r'(t), then, calculate the work of the force. a 0 х В.
