A Review Correct Term 2: Correct answer is shown. Your answer 5.66 m/s was either rounded differently or used a different number of significant figures than required for this part. Learning Goal: To analyze an oblique impact using the conservation of momentum and coefficient of restitution. When an oblique impact occurs between two smooth particles, the particles move away from each other with velocity vectors that have unknown directions and unknown magnitudes. If the y axis is within the plane of contact and the x axis is the line of impact, the impulsive forces of deformation and restitution act only along the line of impact (the x axis). Momentum of the system is conserved along the line of impact (the x axis): Part C Immediately after the collision, what are (VA)2 and (VBy)2, the y components (along the plane of contact) of the velocities for ball A and ball B, respectively?

If the yaxis is within the plane of contact and the x axis is the line of impact, the impulsive forces of deformation and restitution act only along the line of impact (the x axis). Momentum of the system is conserved along the line of impact (the x axis): As shown, tennis ball A rolls off the top of a 10.0 m high wall, falls 4.00 m, and strikes another tennis ball, B. obliquely. (Figure 1) Before the collision, tennis ball Bhas a speed of 21.0 m/s as it moves upward. Each ball”s mass is 57.0 g and the collision”s coefficient of restitution is 0.850. (Figure 2) In the figure, 6 = 30.0° and 1 = 20.0°. What is (VA), the velocity of tennis ball A, immediately before the collision?
