H4.P Given: Disks A and B (of masses m and 2m, respectively) are able to slide freely on a smooth horizontal surface. Disk A moves toward the stationary disk B with a speed of VA1 in the direction shown in the figure. After impact, disk B moves immediately to the left, whereas disk A moves in a direction given by the angle 02. The coefficient of restitution for the impact between the two disk is e and the contacting surfaces between A and B during impact is smooth. Find: For this problem: (a) Derive an expression for the angle 02 in terms of e. (b) Knowing that 0 e 1, use your answer from (a) to determine the range of possible angles 0. B 2m BEFORE impact VA1 0 m A L VB2 B Use the following parameters in your analysis: 0 = 30. VA2 immediately AFTER impact 0
