A falling object satisfies the initial value problem dy dt = 9.8 - (), v0) = 0 where v is the velocity in meters per second. (a) Find the time, in seconds, that must elapse for the object to reach 96% of its limiting velocity Round your answer to two decimal places. ta i 14.9785 (b) How far, in meters, does the object fall in that time? Round your answer to two decimal places. 501.20 m
du Newton's law of cooling is die k(u - T), where (1) is the temperature of an object, fis in hours. Tis a constant ambient temperature, and kis a positive constant Suppose a building loses heat in accordance with Newton's law of cooling. Suppose that the rate constant khas the value 0.18 hr! Assume that the interior temperature is T) = 775, when the heating system fails. If the external temperature is T = 10*F. how long will it take for the interior temperature to fall to T1 = 30*F? Round your answer to two decimal places. The interior temperature will fall to 30*Fin hours.
