Bridging Problem: One Collision After Another © 27 of 27 > Review | Constants Choose the target variables of the problem. Check all that apply. ► View Available Hint(s) mc: mass of sphere C C) velocity of sphere Cafter the second collision Sphere A, of mass 0.600 kg, is initially moving to the right at 4.00 m/s. Sphere B. of mass 1.80 kg, is initially to the right of sphere A and moving to the right at 2.00 m/s. After the two spheres collide, sphere B is moving at 3.00 m/s in the same direction as before. (a) What is the velocity (magnitude and direction) of sphere A after this collision? (b) Is this collision elastic or inelastic? (c) Sphere B then has an off-center collision with sphere C, which has mass 1.60 kg and is initially at rest. After this collision, sphere B is moving at 19.0° to its initial direction at 1.80 m/s. What is the velocity (magnitude and direction) of sphere C after this collision? (d) What is the impulse (magnitude and direction) imparted to sphere B by sphere C when they collide? (e) Is this second collision elastic or inelastic? (f) What is the velocity (magnitude and direction of the center of mass of the system of three spheres (A, B and C) after the second collision? No external forces act on any of the spheres in this problem P(): momentum of sphere B after the first collision O J on B: impulse imparted to sphere B by sphere A during the first collision I Con B: impulse imparted to sphere B by sphere C during the second collision B(1) velocity of sphere B after the second collision (1) velocity of sphere A after the first collision Ücm(ii) velocity of the center of mass of the system of the three spheres after the second collision Ücm(H) velocity of the center of mass of the system of the three spheres after the first collision
