Center of Mass

In the figure below, two particles are launched from the origin of the coordinate system at time t = 0. Particle 1 of mass m1 = 5.00 g is shot directly along an x axis (on a frictionless floor), where it moves with a constant speed of 12.0 m/s. Particle 2 of mass m2 = 3.60 g is shot with a velocity …
