Two balls are approaching each other head-on. Their velocities are +10.50 and -11.2 m/s.

(a) Determine the velocity of the center of mass of the two balls if they have the same mass.

(b) Determine the velocity of the center of mass of the two balls if the mass of one ball (v = 10.50 m/s) is twice the mass of the other ball (v = 11.2 m/s).

Someone help... Please.

anonymous · Answer

a) both of the ball will exchange their velocity
 not sure if what u want is elastic collision(the answer i gave is only for elastic collision)

anonymous · Answer

oh, i gotcha, i use the same equation that you kindly gave me for the other problem I had, which you answered.  Thanks!
