Homework Statement
A coin is dropped from a height of 800 feet. The height, s(measured in feet), at time, t(measured in seconds is given by:
s(t)= Vit + 1/2 a t^2 + So
a) find the average velocity on the interval [1,3]
b) find the instantaneous velocity when t= 3s.
c) how long does it take the coin to hit the ground?
d) find the velocity on the interval [1,3]
Homework Equations
a= -32 ft/s^2
h=800 ft
The Attempt at a Solution
a) I understand that you have to derive the position function to get the velocity function but I'm having trouble doing it. To find the average though i can do f(3)-f(1)/3-1
b) I can't find it because I'm having trouble with the derivative
c &d) I do not understand it because I missed the class that my teacher went over it when i was sick
