1. The following diagram shows a glancing collision of mass 1 and mass 2. Assume that the masses are the same and the surface has no friction. Before Collision After Collision horizontal Mass 2 axis Mass 1 Mass 1 after collision a. Draw a reasonable path for mass 2 after the collision. Explain your reasoning. b. Draw a reasonable path for mass 2 after the collision, if mass 1 is significantly heavier than mass 2. Explain your reasoning.2. Two automobiles collide at an intersection, undergoing a completely inelastic collision as shown in the following image. Car A, with a mass of 1,200 kg, was initially moving at 18 m/s [N], while truck B, with a mass of 1,500 kg, was moving at 20 m/s [W]. Find the final velocity of the two vehicles after they stick together. We S v. =20 m/s v. =18 m/'s3. A stationary atomic nucleus undergoes radioactive decay and a beta particle (a fast- moving electron) and a neutrino (a subatomic particle) are detected leaving the nucleus at high velocities as shown in the following figure. The momentum of the beta particle is 9.2x 10-21 kg.m/s [S] and the momentum of the neutrino is 4.9 x 10-21 kg-m/s [W]. The mass of the remaining nucleus is 3.6 x 10-25 kg. V . p = 4.9 x 10-21 (kg ) m/s [W] o'B p = 9.2 x 10-21 (kg ) m/s [S] a. What is the recoil velocity of the remaining nucleus? b. If the recoil velocity measured is significantly different from the value calculated in part a, what conclusion might a nuclear physicist reach about the decay?4. Object 1, with a mass of 2.0 kg, is sliding along frictionless ice at 12 m/s [E] when it collides with stationary object 2, which has a mass of 3.0 kg. Object 1 moves off at [E 40 N] and object 2 moves off at [E 30' S]. a. Find the magnitude of the velocity of each object, after the collision. b. Was the collision elastic or inelastic? Explain your reasoning. 5. Steel ball A, with a mass of 1.5 kg, is rolling at 4.2 m/s [E] when it collides with stationary 1.2 kg steel ball B. After the collision, steel ball A is moving at 3.3 m/s [E 30 N]. Find the final velocity of steel ball B after the collision
