Exercise 3 Conservation of Momentum I Objects A and B (mA = 6.0 kg and m³ = 2.0 kg) have a head-on collision as shown. Immediately, before the collision, Object A has a velocity of 8.0 m/s to the right and Object B has a velocity of 16 m/s to the left. a. What is the initial magnitude and sign of the momentum for each object? b. What is the total momentum of the two objects (both sign and magnitude)? c. Immediately after the collision, Object A has a velocity of 1.0 m/s to the right. What is the magnitude and direction of the momentum of Object B immediately after the collision? What is its velocity? A a. Two blocks (mA = 6.0 kg and mB = 2.0 kg) are sitting, at rest on a horizontal table with negligible friction between the blocks and the table. The blocks are connected by a compressed spring, which is held together by a string. When the string is cut, the two blocks move away from each other. Use the same scenario as above, except the two objects have a perfectly inelastic collision. In other words, they stick together. What is the magnitude and direction of the momenta of Objects A and B immediately after the collision? b. What are their velocities? a. A A A B B B www.B Before the string is cut, what is the total momentum of the two-block system? b. After the string is cut, which block moves faster? Explain your reasoning. c. What is the ratio of the speeds of the blocks, VA/VB, after the blocks have been separated by the spring?
