Tutorial Exercise Find the work done by the force field F(x, y) = xi + (y + 2)j in moving an object along an arch of the cycloid r(t) = (t - sin(t))i + (1 - cos(t))j, o s t s 2n. Step 1 We know that the work done by the force field F in moving an object along the path C which is parameterized by the vector function r(t) is found by the following equation. W = F . dr For F(x, y) = xi + (y + 2)j and r(t) = (t - sin(t))i + (1 - cos(t))j, we have F(t) = (t - sin(t), 2 - cos(t) x and dr = ( 1 - cos (t) , sin(t) Submit Skip (you cannot come back) Need Help?
