Question

A jogger travels a route that has two parts. The first (A)is a displacement of 1.32 km due south, and the second (B) involves a displacement that points due east. The resultant displacement A+B has a magnitude of 1.77 km. (a) What is the magnitude of B, and (b) what is the direction of A+B as a positive angle relative to due south? Suppose that A-B had a magnitude of 1.77 km. (c) What then would be the magnitude of B , and (d) what is the direction of A-B as a positive angle relative to due south?

Explanation / Answer

A+B is given so is A so use pythagoream theorm .. to find B use same idea for A-B except B is going opposite direction
