A model for the startup of a runner in a short race results in the velocity function

Question:

A model for the startup of a runner in a short race results in the velocity function v(t) = a(1 - e-t/c), where a and c are positive constants and v has units of m/s.

a. Graph the velocity function for a = 12 and c = 2. What is the runner’s maximum velocity?

b. Using the velocity in part (a) and assuming s(0) = 0, find the position function s(t), for t ≥ 0.

c. Graph the position function and estimate the time required to run 100 m.
