Car 1 has a mass of 65000 kg and moves at a veloctiy of 0.80 m/s. Car 2 with a mass of 92000 kg and a velocity of 1.2 m/s, overtakes Car 1 and couples to it. Neglecting friction, find the common velocity of the two cars after they become coupled.

At an oceanside nuclear power plant, seawater is used as part of the cooling system. this raises the temperature of the water that is discharged back into the ocean. the amount that the water temperature is raised has a uniform distribution over the interval from 10° to 25° c. what is the standard deviation of the temperature increase?
