Question 115060:  What is the velocity of a bullet? 
if a gun is fired straight upward, the bullet leave the gun at 100 feet per second, after 2 seconds the velocity of the bullet is 36 feet per second? 
there is a linear equation that give the velocity in terms of the time
 
Find the equation and the velocity after three seconds?

You can  put this solution on YOUR website! if a gun is fired straight upward, the bullet leave the gun at 100 feet per second, after 2 seconds the velocity of the bullet is 36 feet per second? 
there is a linear equation that give the velocity in terms of the time
 
Find the equation and the velocity after three seconds?  
--------------------- 
You have two points relating velocity to time: (0,100) and (2,36) 
------------ 
Slope = (100-36) / (0-2) = -32 
----------------- 
Intercept: f(0) = 100 
-------------- 
EQUATION: 
velocity = -32 t + 100 
================== 
v(0)=100 
---------------- 
v(3) = -32*3 + 100 = 4 ft. per sec. 
===============
