you want s'(0)

the velocity function is the derivative of the position function

you want to solve v(t) = s'(t) = 0The particle stops moving (i.e. is in a rest) twice, once when and again when where . is

and is

s(18)What is the position of the particle at time ?

if you have learned integrals, this isFinally, what is the TOTAL distance the particle travels between time and time ? ........how do we find the total distance???????
