A child is splaying with a toy aero plane. the aero plane is flying with velocity (6i + 2j)m/s. A breeze begin to blow with velocity 0.5j m/s affecting the motion of the aero plane.

a) find the magnitude of the resultant velocity of the plane

b) find the angle this resultant velocity makes with the unit vector i

(6,2) + (0,.5) = (6,2.5)

|6,2.5| = 6.5

tanθ = 2.5/6

θ = 22.6°
