3. Antiderivatives and initial value problems (a) Let $f^{\prime \prime}(x)=-5$ i. Find $\int f^{\prime \prime}(x) d x$ . ii. Find $f^{\prime}(x)$ and $f(x)$ given that $f^{\prime}(1)=2$ and $f(1)=8$ . (b) Suppose you are driving at 12 meters $/ \mathrm{sec}$ . You see a turtle ahead, so you slam on the breaks, bringing your car to a complete stop in just 6 meters. Let's figure out what constant deceleration was needed to make this happen: i. Assume the constant acceleration is $a(t)=-k$ (negative becuase the car is slowing down). At the start of the problem you were driving at $12 \mathrm{~m} / \mathrm{s}$ , so the initial condition is $v(0)=12$ . Use this information to find the velocity function $v(t)$ . (Your answer will involve $k$ .) ii. Find the position function $s(t)$ given the initial condition $s(0)=0$ . (Your answer will still involve $k$ .) iii. Use the function $v(t)$ that you found above to determine the time $t$ at which the cal came to a stop. iv. Use the function $s(t)$ that you found above to find $k$ . (Hint: $s=6$ at the time wher the car came to a stop.) What constant deceleration did you use to make the car stop
