Ī) Where does f(x) have a relative minimum?ī) Where does f(x) have a relative maximum?Ĭ) If f(x) has an inflection point, approximately where does it lie?Ī) This function has a relative minimum at x = 0. t = 5.76 is one of several possibilities. The initial time, t=0 gives us a position: x(0) = 0-cos(0)-.839 = -1.839ĭ) Simply find a root for our initial equation for velocity. To solve for c, we need to know one point: At time t=10, the car is at a position x = 5. Therefore, the object is slowing down.Ĭ) Now we need to take the indefinite integral to get a function of position. However you should learn how to use you graphing calculator to do this question because many integrals will be far more difficult.ī) Slowing down and speeding up are questions about whether or not the acceleration is positive or negativeĬos(t) is negative when t = 10. This is an integral that can easily be done by hand. The total displacement therefore in the integral of the velocity function between the bounds given Ī) What is the total displacement of the car between the times t = 0 and t=5ī) At time t = 10, is the car slowing down, or speeding up?Ĭ) What is the position of the particle at the initial time?ĭ) Find a time when the velocity equal to 0.Ī) Whenever we have a velocity question, we should think back to the following relationships: At time t=10, the car is at a position x = 5. Its velocity can be modeled by the equation. An object moves back and forth across the x-axis. AP Calculus AB Exam Free Response Practice Problems 1.
