ra A jogger travels a route that has two parts. The first is a displacement of 2.85 km due south and the second involves a displacement B that points due east. The resultant displacement + B has a magnitude of 3.95 km. (a) What is the magnitude of Band (b) what is the direction of B as a positive angle relative to due south? Suppose that had a magnitude of 3.95 km. (c) What then would be the magnitude of Band (d) what is the direction of relative to due south? + (a) Number Units (b) Number Units (c) Number Units (d) Number Units
