Two identical cars A and B are at rest on a loading dock with brakes released. Car C, of a slightly different style but the same weight, has been pushed by dockworkers and hits car B with a velocity of 4.5 ft/s. Knowing that the coefficient of restitution is 0.8 between B and C, and 0.5 between A and B, Determine the velocity of each car after all collisions have taken place.
an air-standard otto cycle uses 0.1 kg of air and has a clearance of 17%. THe intake conditions are 98 kPa and 37 C and the energy released during combustion is 1600 KJ/kg. What is the compression ratio of the cycle?
