A collision occurs between a 1.29 kg particle traveling with velocity = (-4.75 m/s )+(-5.57 m/s) and a 3.76 kg particle traveling with velocity V2 = (6.35 m/s )+(-2.10 m/s). The collision connects the two particles. What then is the (a)x component and (bly component of their velocity? Express their velocity as a (c) magnitude and (d) angle (in the range (-180, 180)) from the +x axis?
