Question 8 • Physics

Assuming motion is on a straight path, what would result in two positive components of a vector?

Answer
A
a boat moving south of west at an angle of 40 degrees
B
a car moving south of west at an angle of 10 degrees
C
a bus moving north of east at an angle of 95 degrees
D
a train moving north of east at an angle of 25 degrees

Explanation

A vector has two positive components when it points in the positive x- and positive y-directions. A direction described as 25 degrees north of east points mostly east and partly north, so both components are positive. Thus, the train moving north of east at 25 degrees is correct. The 95-degree direction is beyond north, while directions south of west have negative components.
