Ap calculus ab 201412/13/2023 ![]() ![]() Find the rate, in meters per minute, at which the distance between train A and train B is changing at time t = 2. At time t the velocity of train B is given by V B(t) = -5t 2 + 60t + 25 and at time t = 2 the train is 400 meters north of the station. (d) A second train, train B, travels north from the Origin Station. Use a trapezoidal sum with three subintervals indicated by the table to approximate the position of the train at time t = 12. Write an expression involving an integral that gives the position of train A, in meters from the Origin Station, at time t = 12. (c) At time t = 2, train A’s position is 300 meters east of the Origin Station, and the train is moving to the east. (b) Do the data in the table support the conclusion that train A’s velocity is -100 meters per minute at some time t with 5 < t < 8 ? Give a reason for your answer. ![]() (a) Find the average acceleration of train A over the interval 2 ≤ t ≤ 8. Selected values for V A(t) are given in the table above. Train A’s velocity, measured in meters per minute, is given by a differentiable function V A(t), where time t is measured in minutes. Train A runs back and forth on an east-west section of railroad track.Then we are in the same situation as in Problem 2 of 2014 Spring Real. Show the work that leads to your answer.ĪP Calculus AB 2014 Free Response Question 4 math score of 29 or above on the ACT You scored 3 on the AP Calculus AB test. Use L(t) to predict the time at which there will be 0.5 pound of grass clippings remaining in the bin. (d) For t > 30, L(t), the linear approximation to A at t = 30, is a better model for the amount of grass clippings remaining in the bin. (c) Find the time t for which the amount of grass clipping in the bin is equal to the average amount of grass clipping in the bin over the interval 0 ≤ t ≤ 30. Using correct units, interpret the meaning of the value in the context of the problem. (a) Find the average rate of change A(t) over the interval 0 ≤ t ≤ 30. For 0 ≤ t ≤ 30, the amount of glass clippings remaining in the bin is modeled by A(t) = 6.687(0.931) t, where A(t) is measured on pounds and t is measured in days. Grass clippings are placed in a bin, where they decompose.Questions and Worked Solutions for AP Calculus AB 2014ĪP Calculus AB 2014 Free Response Questions - Complete Paper (pdf)ĪP Calculus AB 2014 Free Response Question 1Ī graphing calculator is required for these problems. ![]()
