Question: Two particles P and Q are released from rest l.0 m apart. P has a mass of 0.10 kg, and Q a mass of 0.30

Two particles P and Q are released from rest l.0 m apart. P has a mass of 0.10 kg, and Q a mass of 0.30 kg. P and Q attract each other with a constant force of 1.0 x 10-2 N. No external forces act on the system.

(a) What is the speed of the center of mass of P and Q when the separation is 0.50 m?

(b) At what distance from P's original position do the particles collide?
