Sphere A has a weight of 37 lb and a radius of 7 in., while sphere B has a weight of 7 lb and a radius of 5 in. If the spheres are traveling initially along the parallel paths with the speeds shown, determine the velocities of the spheres immediately after impact. Specify the angles A and B with respect to the x- axis made by the rebound velocity vectors. The coefficient of restitution is 0.55 and friction is neglected. Enter positive numbers for the angles e. A Answers: VA = y 19 ft/sec 65 ft/sec B X 7" ft/sec, A = ft/sec, 0B = VB =
