Hello here I am giving you AP Calculus BC Free-Response Questions:

1. The temperature of water in a tub at time t is modeled by a strictly increasing, twice-differentiable function W,
where W t is measured in degrees Fahrenheit and t is measured in minutes. At time 0, t the temperature of
the water is 55 F. The water is heated for 30 minutes, beginning at time 0. t Values of W t at selected
times t for the first 20 minutes are given in the table above.
(a) Use the data in the table to estimate 12 . W Show the computations that lead to your answer. Using correct
units, interpret the meaning of your answer in the context of this problem.
(b) Use the data in the table to evaluate 20
0
. W t dt Using correct units, interpret the meaning of 20

W t dt
in the context of this problem.
(c) For 0 20, t the average temperature of the water in the tub is 20

20
W t dt Does this
approximation overestimate or underestimate the average temperature of the water over these 20 minutes?
Explain your reasoning.
(d) For 20 25, t the function W that models the water temperature has first derivative given by
0.4 cos 0.06 . W t t t Based on the model, what is the temperature of the water at time 25 ?


2. For 0, t a particle is moving along a curve so that its position at time t is , . x t y t At time 2, t the
particle is at position 1, 5 . It is known that 2

(a) Is the horizontal movement of the particle to the left or to the right at time 2 ? t Explain your answer.
Find the slope of the path of the particle at time 2. t
(b) Find the x-coordinate of the particle’s position at time 4. t
(c) Find the speed of the particle at time 4. t Find the acceleration vector of the particle at time 4. t
(d) Find the distance traveled by the particle from time 2 t to 4. t
