Chapter 14.1, Problem 14.13P

A system consists of three particles A, B, and C. We know that m_A = 3 kg, m_B = 2 kg, and m_C = 4 kg and that the velocities of the particles expressed in m/s are, respectively, v_A = 4i + 2j + 2k, v_B = 4i + 3j, and v_C = −2i + 4j + 2k. Determine the angular momentum H_O of the system about O.

Collision at an Angle To apply conservation of linear momentum in an inelastic collision. Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at a speed 2v, while the second was traveling in a southeastern direction at an angle ϕ with respect to the east-west direction and at a speed v. After the collision, the two-car system travels in a northeastern direction at an angle θ with respect to the north-south direction and at a speed v final. Find v final, the speed of the joined cars after the collision. Express your answer in terms of v and ϕ.

After the collision, the two-car system travels in a northeastern direction at an angle θ with respect to the north-south direction and at a speed v final. What is the angle θ (with respect to north) made by the velocity vector of the two cars after the collision? Express your answer in terms of ϕ. Your answer should contain an inverse trigonometric function.

4. Two blocks with the same mass are connected to a compressed spring at opposite ends. At first, the spring and blocks slide at the same velocity v on a frictionless surface to the right. The spring is released and at some later instant the left block is moving at v/2 to the left and the other block is moving to the right. What the speed of the center of mass of the system at that instant? (A) 5v/2 (B) 3v/2 (C) v (D) v/2
