A 1500kg car traveling at 100km/h south collides with a 1200 kg car traveling north at 100km/h. The heavier car continues to move south after the collision, but slows to 25.0km/h. How fast is the lighter car moving after the collision? Please help!!

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r
