Determine an expression for vector A and determine the magnitude and direction of A.

Part 1
Vector A has a negative x component 3 units in length and a positive y component of 2 units in length.

1. Determine an expression for vector A in unit vector notation
2. Determine the magnitude and direction of A.

Part 2
what vector B when added to A will give a resultant vector with no x component and a negative y compnent 4.0 units in length?
