Question 4 Some people are not functionally impaired now, but their pulmonary function usually declines with age and they eventually will be functionally impaired. Assume that the decline in FEV over n years is normally distributed, with mean = 0.03n L and standard deviation = 0.02n L. What is the probability that a 45-year-old man with an FEV of 4.0 L will be functionally impaired by age 75? (Please answer to 3 decimal places: e.g. 0.123) Hint: 75-45 = 30 years of decline, so mean = 0.03(30) = 0.9L Hint 2: Since the man was initially 4.0L, he would be functionally impaired at age 75 if he declines by at least 1.5L.

(a) Suppose a mass m slides without friction on a horizontal surface. The dough is stuck to a spring with constant k, as illustrated in the figure below, and is also subjected to resistance viscous air with coefficient \gamma. Formulate the initial value problem that describes the displacement u(t) of the mass from its equilibrium position.
