Question

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 $\theta_A$ and $\theta_B$ 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 $\theta$. y $\theta$ x A 19 ft/sec 7" Answers: 65 ft/sec B $v_A = $$ $ft/sec, \theta_A = $ $v_B = $ $ft/sec, \theta_B = $
