The average velocity of an object with position function

s(t)

on the interval

a,t

is

/bar (v)=(\Delta s)/(\Delta t)=(s(t)-s(a))/(t-a)

Given the position function below.

s(t)=-16t^(2)+73t+128

Find the average velocity

ho ^(ff)

the projectile on the interval

3,t

.

v(t)=

The instantaneous velocity of an object with position function

s(t)

at

t=a

v(a)=(ds)/(dt)=\lim_(t->a)(s(t)-s(a))/(t-a)

Find the instantaneous velocity of the projectile at

t=3

.
