# Vectors watch

1. An object in the plane is subjected to two forces. The first F1 has magnitude 5N and
direction pie/4 to the left of the positive y-axis. The second F2 has magnitude 20N. If
the resultant force on the object has direction pie/4 to the right of the positive y-axis,
find the direction of F2 (in radians, to 3dp).

2. hmm i think this question tells u that the resultan force and F1 has a pi/2 angle between them..that means you can form a nice triangle and solve it... my answer is 0.54 radians to the right of the positive y achsis... can somebody check this answer?
3. Hmm i still dont understand this at all. Can someone explain how to solve this problem more fully? Cheers
4. 2pi radians = 360 degrees ?

To find the correct answer, we must ask the right question. What is 'pie'?
