Velocity of a bullet. 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. Find the equation and find the velocity after 3 seconds.
