Question
The picture above is a snapshot at time t = 0 showing three balls, labelled A, B, and C. The distance between ball B and ball A at t = 0 is the same as the distance between ball B and ball C at t = 0 (d = 12.0 m). In the reference frame of the table, balls B and C each move to the left with constant velocities of VB = -4.0 m/s and Vc = -35.0 m/s, respectively. Ball A moves to the right with a constant velocity VA = +18.0 m/s. For the following questions, to the right is positive and to the left is negative. From the reference frame of ball A, what is the velocity of ball B? m/s Which ball collides with ball B first? Ball A Ball C Ball A and Ball C collide with Ball B at the same time.Explanation / Answer
v(B/A)=-4-18=-22 m/s c collides first
