A jogger runs halfway around a circular path with a radius of 70 m.What,respectively,are the magnitude of the displacement and the distance jogged?
A) 70 m,220 m
B) 70 m,440 m
C) 140 m,220 m
D) 140 m,440 m

The magnitude of the displacement is equal to the diameter of the circle, which is 2r = 2(70m) = 140m. To find the distance jogged, we need to find the length of half the circumference, which is (1/2)(2πr) = πr = (3.14)(70m) = 220m. Therefore, the answer is C) 140m, 220m.
