A jogger travels a route that has two parts. The first is a displacement A of 2.90 km due south, and the second involves a displacement B that points due east.for part1:(1) The resultant displacement A + B has a magnitude of 4.55 km. What is the magnitude of B?
What is the direction of A + B relative to due south?
(2) Suppose that A - B had a magnitude of 4.55 km. What then would be the magnitude of B and what is the direction of A - B relative to due south?
direction of A - B relative to due south
B = 5.395 km
some how that answer is wrong, can someone explain?
