Two particles P and Q are initially at rest 1.64 m apart, P has a mass of 1.43 kg and Q a mass of 4.29 kg. P and Q attract each other with a constant force of 1.79 x 10-2 N. No external forces act on the system. (a) Describe the motion of the center of mass. (b) At what distance from P’s original position do the particles collide?

(a) The center of mass of the system has no acceleration, and remains at the same position as it was earlier.
(b) Assume that the origin of the coordinate system is at the position of particle P, then the center of mass of the system is given as: 236-782_1.PNG
