1. Two points in a plane have polar coordinates (2.5 m, 30 degrees) and (3.8 m, 120 deg). Determine (a) the cartesian coordinates of both points and (b) the distance between the points.

2. Vector A has magnitude 29 units and points along +y. When vector B is added to the vector A, the resultant ponits along -x with a magnitude of 14 units. Find the magnitude and directions of B.

3. Repeat #2, for the same vector A, but for the case where the resultant of A and B points along -y with a magnitude of 14 units .
