Please answer question 4, as it requires data from question 3. I have included question 3 below for your reference.

4. Same as Problem 3, but write out the position vector vector calculus r(t) and the force field F(t) in Cartesian coordinates. Jim Compute the work done using Cartesian unit vectors. 3. A particle experiences a force field that may be written in spherical coordinates as F = -40e+leg. Under the influence of this force field, this particle moves from the north pole vector calculus to the equator on a sphere of radius 2. Its coordinates, as a function of time, are: r(t) = 2, 0(t) = t, 4(t) = 1 /2, OstS n/2. Compute the work done, W= F.dr , by the force field in moving the particle by using spherical coordinates and unit vectors
