A race car is traveling on a straight track. The velocity of the race car, denoted by $v(t)$, is given by the function $v(t) = 100 - 2t$, where $t$ represents the time in seconds since the start of the race and $v(t)$ $v(t)$ is the velocity of the race car in meters per second. The race car starts from rest at $t = 0$ seconds. The driver of the race car wants to determine the total distance travelled by the race car over the time interval from seconds to $t = 25$ seconds. Provide a step-by-step solution to calculate the total distance travelled by the race car over the specified time interval.

Find the domain of the vector functions, r(t), listed below. You may use \"-INF\" for $-\infty$ and use \"INF\" for $\infty$ as necessary, and use \"U\" for a union symbol if a union of intervals is needed. a) r(t) = $\langle \ln(1t), \sqrt{t+17}, \frac{1}{\sqrt{12-t}} \rangle$ b) r(t) = $\langle \sqrt{t-8}, \sin(2t), t^2 \rangle$ c) r(t) = $\langle e^{-8t}, \frac{t}{\sqrt{t^2-4}}, t^{1/3} \rangle$
