A billiard ball traveling at 8.0 m/s has an elastic collision with a second billiard ball of equal mass that is at rest. After
the collision, the first ball is at rest. What is the velocity of the second ball after the collision?

  • physics - ,

    v1=8m/s, v2=0 , m1=m2->m , v=?
    m1*v1+m2*v2=(m1+m2)*v
    m*8+m*0=(m+m)*v
    8m=2m*v
    8m/2m=v
    4=v

    v=4m/s
