9 1 point A 55kg cyclist on a 10kg bicycle starts coasting on level ground at 25m/s. Use v = voe m, where k is about 3.9kg/s. 1. About how far will the cyclist coast before reaching a complete stop? Ans: type your answer... m (Round to the nearest tenth if necessary.) ? 2. How long will it take the cyclist's speed to drop to 1m/s? Ans: type your answer... s (Round to the nearest hundredth if necessary.) 10 1 point A tank initially contains 100 gal of brine in which 50 g of salt are dissolved. A brine containing 2 g / gal of salt runs into the tank at the rate of 5 gal / min. The mixture is kept uniform by stirring and flows out of the tank at the rate of 4 gal / min. Let y(t) be the amount of salt in the tank at time t in minutes. Then the rate of salt entering the tank satisfies a first order choose your answer... V differential system given by y' (t) + P(t)y(t) = Q(t), where P(t) is a choose your answer... V and Q(t) is a choose your
