balls of al ter 5 m each moving th a speed 01 3 roll without slipping towards each other on a horizontal rectangular U shaped trough that is sufficiently deep that the balls are clear of its base see figure The resulting instantaneous collision is perfectly elastic and during it each ball reverses its linear velocity through their angular velocities are not affected Answer A B C Your Attempt Correct answer When width 4 cm the balls will collide twice When width 3 cm the balls will collide twice Rate this question speed of the balls just before the second collision if the width of the trough is 4 cm is 0 16 m s
