A collision occurs between a 4.44 kg particle traveling with velocity 1 = (6.40 m/s) +(-1.18 m/s) and a 1.49 kg particle traveling with velocity 1 = (-4.64 m/s) + (-4.46 m/s). The collision connects the two particles. What then is the (a) x component and(b)y component of their velocity? Express their velocity as a (c) magnitude and (d) angle from the +x axis?
