The three balls in the overhead view of Fig. 2 are identical.Balls 2 and 3 touch each other and are aligned perpendicular to thepath of ball 1. The velocity of ball 1 has magnitude 10 m/sand is directed at the contact point of balls 1 and 2. After thecollision, what are the (a) speed and (b) direction of the velocity of ball2, the (c) speed and (d) direction of the velocity of ball 3, and the (e)speed and (f) direction of the velocity of ball 1? (Hint: With frictionabsent, each impulse is directed along the line connecting the centersof the colliding balls, normal to the colliding surfaces.) fig
