An object moving on the x axis with a constant acceleration increases its x coordinate by 161 m in a time of 12.5 s and has a velocity of 20 m/s at the end of this time.

Question

Determine the acceleration of the object
during this motion.
Answer in units of m/s2.

Answer 1

-2 X (161-20 X 12.5) / 12.5^2
=1.139
