The two particles A and B start at the origin O and travel in opposite directions along the circular path at constant speeds vA = 0.7 m/s and vB = 1.5 m/s, respectively. Determine in t – 2 s, (a) the displacement along the path of each particle, (b) the position vector to each particle, and (c) the shortest distance between the particles.
