a gun is fired straight upward. the bullet leaves the gun at 100 feet per second (time t=0) after 2 seconds the velocity of the bullet is 36 feet per second there is a linear equation that gives the velocity v in terms of the time t.
-----------------------
You have two points relating time and velocity:
(0,100) and (2,36)
slope = (36-100)/(2-0) = -32
---
intercept = 100
---------------------
Equation:
velocity = -32(time) + 100
-------------
Find the velocity after 3 seconds.
v(3) = -32(3) + 100
v(3) = -96+100
v(3) = 4 ft/sec
