The bus B has weight { W }_{ B } and is traveling to the right at speed { v }_{ B } . Meanwhile car A of weight { W }_{ A } is traveling at speed { v }_{ A } to the left. If the vehicles crash head-on and become entangled, determine their common velocity just after the collision. Assume that the vehicles are free to roll during collision.Given: { W }_{ B } = 15000 lb , { v }_{ B } = 5 ft/s , { W }_{ A } = 3000 lb , { v }_{ A } = 4 ft/s , g = { 32.2ft/s }^{ 2 }
