Homework Help: AP Physics Kinematics 2 Balls Inclined Track

Tags:
  1. Sep 23, 2012 #1
    Consider two balls on an inclined track with a constant angle. Ball A is released from rest at the top of the track. Ball B is given an initial velocity directed down the track. At the instant that the balls collide, Ball A is going 4 times as fast as Ball B. Ball B is still traveling upward along the track at the time of the collision. At what fraction of the way along the track, measured from the bottom, does the collision occur? (Draw a graph of velocity versus time showing motion of both balls. Show all work)



    At least a drawing of velocity versus time, identify the variables, label the graph carefully. But main question is "At what fraction of the way along the track, measured from the bottom, does the collision occur?"
