1. The problem statement, all variables and given/known data Three displacement vectors of a croquet ball are shown in the figure, where |a vector| = 22.0 units, |b vector| = 25.0 units, and |c vector| = 10.0 units. (a) find the resultant in unit-vector notation ____ i hat + ____ j hat (b) Find the magnitude and direction of the resultant displacement. ____ units ____ ° (from the +x axis) 2.
