MOCO Homework: Determine Avg Velocity

[ajayespinoza]

Homework Statement

An automatic guided vehicle is traveling at a speed of 12 ft/sec when it is ordered to stop. It uniformly decelerates to a stop in 18ft
Determine the average velocity

Homework Equations

(Initial speed-final speed)/ total time taken = decelerations

The Attempt at a Solution

avg velocity of 12 ft/sec/sec is 6
18/6 = 3
3x4 = 12
so the avg velocity is 4 ft/sec/sec

(Is this the first part of a longer question? )

Hint: average speed = (Initial speed+final speed) divided by … ?
