At noon the air conditioner is turned off, and the people go home. The temperature outside is a constant 36°C for the rest of the afternoon. If the time constant for the building is 3 hr, what will be the temperature inside the building at 3:00 P..? At 5:00 P.M.? When will the temperature inside the building reach 27°C? At 3:00 P.M., the temperature inside the building will be about c. (Round to the nearest tenth as needed.) Homework: HW 5 - Applications of first order ODES Question 8, 3.4.13 Part 2 of 2 HW Score: 62.5%, 7.5 of 12 points Points: 0,5 of 1 Save When the velocity v of an object is very large, the magnitude of the force due to air resistance is proportional to v2 with the force acting in opposition to the motion of the object. A shell of mass 4 kg is shot upward from the ground with an initial velocity of 600 m/sec. If the magnitude of the force due to air resistance is (0.1)v2 when will the shell reach its maximum height above the ground? What is the maximum height? Assume the acceleration due to gravity to be 9.81 m/s? When will the shell reach its maximum height above the ground? The shell will reach maximum height after 3.11 seconds. (Round to two decimal places as needed.) What is the maximum height? The maximum height is 136 m. (Round to the nearest whole number as needed)
