Two balls are involved in a completely inelastic collision. The first ball has a mass of 0.25 kg and an initial velocity of 9.27 m/s in the x-direction The second ball has a mass of 0.50 kg with an initial velocity of 2.61 m/s in the -x-direction. What is the speed of the two balls after the collision in m/s?

  • Physics -

    m1•v1- m2•v2 =(m1+m2) •u,
    u= (m1•v1- m2•v2)/(m1+m2)
