Find y = f(x) if f''(x) = x2 , f'(0) = 7, and f(0) = 2. 15. Use a (t ) = −32 ft / sec 2 as the acceleration due to gravity. A ball is thrown vertically upward from the ground with an initial velocity of 96 feet per second. How high will it go? 16. Use a (t ) = −32 ft / sec 2 as the acceleration due to gravity. A ball is thrown vertically upward from the ground with an initial velocity of 56 feet per second. For how many seconds will the ball be going upward? 17. An object has a constant acceleration of 72 feet per second squared, an initial velocity of 17 feet per second, and an initial position of 10 feet. Find the position function describing the motion of this object. 18. Scherer 3 dP = 50t 2 − 100t 2 where P is dt the population size and t is the time in years. The initial population is 25,000. Find the population function. Then use a graphing utility to graph the function, and then use the graph to estimate how many years it will take for the population to reach 50,000. The rate of growth of a particular population is given by Page 2 12/21/2005 19. Write the definite integral that represents the area of the region enclosed by y = 4 x − x 2 and the x-axis. 20.
