2. Consider the work integral (y – a?) da + (1 – x) dy. Consider the following two paths that start at
(-1,1) and end at (3,9):
(-1+ 4t, 1+ 8t), 0<t<1
(t, t2), –1 <t<3
(a) Along which path would the field do more work on the particle?
(b) Why do the two paths produce a different amount of work?
(c) A particle moves from (-1, 1) to (3,9) along the first path, and then from (3, 9) back to (-1,1)
