l. (11 points) Let C1 be the directed line segment that starts at (2, 0) and ends at (3, 5) and Cg he the parabola with parametrization a: = t, y = 4 t2 for t E [3, 2]. Let F be the vector eld .0 F(.1:,y) = (I2 4y) i + (23:: + 33,3) 5?. (a) Evaluate fCl 13-1117. (b) Evaluate f0 F-df' where C is the positively oriented path consisting of the parabola y = 4532 starting from (2,0) to (3, 5) and the line segment from (3, 5) back to (2,0). ((3) Use the results in (a) and (b) to evaluate 1.02 f5 - dF
