You have been assigned to investigate a traffic accident. The masses of car A and car B are 1300 kg and 1200 kg, respectively. Car B was initially at rest with all four wheels locked. Skid marks indicate car B slid 10 m after the impact. Assuming that the coefficient of kinetic friction the tires and road is 0.8 and the coefficient of restitution of the impact is 0.4, calculate the velocity of A just before impact.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
