Math 2400: Calculus III Line Integrals over Vector Fields (c)Find a vector in the direction of the path that is travelled over a time inteveral of length t. Draw this vector on the graph as a typical short segment of the path. (Note that we are looking for r, and that r0(t) ˇ r t.) Solution:r0(t) = h 2 p 2sint;2 p 2costi.
Calculating work done when the force eld is not constant and the path is not linear. Now we'll nd the work done by a force eld F(x; y) = h y; p xi in moving an object along a semi-circular counter-clockwise path from ( 2; 2) to (2; 2) (the radius is 2 2). The force eld and the path are shown below. -3 -2 -1 0 1 2 3.
Explain what is meant by the vector projection of one vector onto another vector, and describe how to compute it. Calculate the work done by a given force.
