Q. An object travels along a straight line. The function

s(t) = -9.8t^2 + 18t + 100

gives the object's position, in feet, at time

t

seconds.

\newline

Write a function that gives the object's velocity

v(t)

in feet per second.

\newline

v(t) = ______

Differentiate $s(t)$ for $v(t)$ : To find the velocity function $v(t)$ , we need to differentiate the position function $s(t)$ with respect to time $t$ .
