An object follows as shown below. What is the displacement from the last point to the starting point? Express your answer (a) in unit vector notation, and (b) as a magnitude and direction

Three displacement vectors of a croquet ball are shown in Figure P3.22, where 1AI = 20.0 units, IBI = 40.0 units, and ICI = 30.0 units. Find (a) the resultant in unit-vector notation and (b) the magnitude and direction of the resultant displacement.
