Problem 15.104
Two smooth disks A and B are both moving with speed vo in the directions shown when they collide. If the mass of B is mg, the mass of
A is mA, and the coefficient of restitution for the impact is e, determine, as functions of e, mA, MB, Vo, and 8, the postimpact components
of the velocities of A and B along the line of impact. If e = 2/3 and 0 = 60°, determine the minimum value of the mass ratio m/m³ that
ensures that the postimpact speed of B is greater than vo. Use cos 60° = 1/2 and sin 60° =
= √√312.
