Please help me with this question; A certain force F= 20N ^i + 40N ^j is applied to an object which proceeds to move 1.0m along the negative x-axis and 3.0m along the positive y-axis. It does this because there are other forces on this object, but we will not need to think about those other forces a.) Write down ( math symbol that looks like a triangle) r in component form. b.) Determine the work done by this

a.) Write down ( math symbol that looks like a triangle) r in component form.
b.) Determine the work done by this force F using the definition of dot product
c.) Find the magnitudes of the vectors F and ( math symbol that is a triangle) r using the Pythagorean theorem.
d.) calculate the angle 0 between F and ( triangle) r by utilizing your answer to part (b) and the other definition of dot product. Roughlly, sketch the two vectors to make sure that angle I reasonable
