In a classic Seinfeld episode, Jerry tosses a loaf of bread (a marble rye) straight upward to his friend George who is leaning out of a third-story window.
a. If the loaf of bread leaves Jerry’s hand at a height of 1 m with an initial velocity of 18 m/sec, write an equation for the vertical position of the bread s (in meters) t seconds after release.
b. How long will it take the bread to reach George if he catches the bread on the way up at a height of 16 m? Round to the nearest tenth of a second.

- The population P (in millions) of Texas from 2001 through 2014 can be approximated by the model P=20.913e0.0184t, where t represents the year, with t=1 corresponding to 2001. According to this model, when will the population reach 32 million?arrow_forwardResearchers in Alaska have developed models that can be used to estimate the mass of a polar bear. For bears that are caught in the spring of the year M(x, y) = 0.000199x1.2823y1.4874, where M(x, y) is the mass of the bear (in kg), x is the straight-line body length (in cm), measured from the tip of the nose to the base of the tail, and y is the girth (in cm), measured directly behind the shoulders.

- The accompanying graph plots the best quadratic fit, a(t) = − 0.70t^2 + 1.44t + 10.44, to the data from the preceding table. Compute the average value of a(t) to estimate the average acceleration between t=0 and t=5.arrow_forwardGiven the acceleration of an object and its initial velocity, how doyou find the velocity of the object, for t ≥ 0?arrow_forward
