2.) The components of vector ⃗ are given as follows: Ax = 5.6 Ay = -4.7
What is the angle between vector ⃗ and positive direction of x – axis?

The scalar x-component of a vector can be expressed as the product of its magnitude with the cosine of its direction angle, and the scalar y-component can be expressed as the product of its magnitude with the sine of its direction angle. In a plane, there are two equivalent coordinate systems.

Explanation:

there are no contact forces mentioned on the list of choices that you've provided.
