Homework Statement
An object moving on the x-axis with a constant acceleration increases its x coordinate by 80 m in a time of 5.0 s and has a velocity of +20 m/s at the end of this time. Determine the acceleration of the object during this motion.
x = 80m t = 5.0 second v = + 20m/s a = while in motion
Homework Equations
80 m = 100 m + 1/2 a 25 s2
-1.6 m/s2
The Attempt at a Solution
Supppos to be positive I don't know why I get negative acceleration?
