Two identical objects, one moving twice as fast as the other, collide with each other in the following way:
0--------> 2v v <----0
m m
If the two objects stick together after the collision, will they be moving to the right, to the left, or not at all? Explain your answer.

  • Physics -

    m1•v1 – m2•v2 =(m1+m2)u.
    m•2•v – mv = 2•m•u,
    u = m•v/2•m = v/2 (to the right)
