Learning activity 2.5: Understanding momentum in two dimens:cns MINDS ON ACTION CONSOLIDATION practice set problems and submit your solutions to check for understanding. 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. @ = horizontal Mass 2 axis S 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
