1.A typical motorcycle emits about 20 g of CO per mile. What volume of CO would a 5-mile trip produce after the gas coolsto 25°C (at 1 atm) and per meter of distance traveled, what volume of air could be polluted to the air quality standard of 9ppm?

2.A sled with two runners slides along a thin horizontal layer ofwater between the ice and the runners. The horizontal force thatthe water puts on the runners is equal to 1.2 lb when the sled'sspeed is 30 ft/s. The total area of both runners in contact withthe water is 0.08 ft2, and the viscosity of the water is3.5x10-5 lb*s/ft2. Determine the thickness of the water layer under the runners. Assume a linear velocity distribution in the water layer.

3.A train starts from station A and for the first kilometer, it travels with a uniform acceleration. Then for the next two kilometers, it travels with a uniform spped. Finally, the train decelerates uniformly for another kilometer before coming to rest at station B. If the time for the whole journey is six minutes, draw the v-t graph and determine the maximum speed of the train
