Jogger A goes north at 4 mph and joggers b goes east at 6 mph. After 3 seconds, what is the relative velocity of jogger A with respect to jogger B? Solution Relative Velocity Vector Location does not matter, relative velocity will be the same at t = 0 or t = 3 secs.      vA = vA/B + vB      4j = vA/B + 6i vA/B = -6i + 4j mph
