Adoor-door salesperson sells snow shovels and snow blowers, and can drive up to 9500km per week (tough because snowblowers can be shared among neighbors, the salesperson has to drive an average of 20km to sell a snowblower, but only 5km to sell a snow shovel. the salesperson can work up to 40 hours/week, and it takes an average of 0.05 hours to sell a snowblower (because they practically sell themselves), but 0.12 hours to sell a snow shovel (who wants to each snowblower weighs 25kg while each shovel weighs 2kg, and the salesperson can only carry 6500kg per week on the truck. when sold, a snowblower yields $45 in profit, while a snowshovel only yields $5 in profit.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
