If an object with uniform acceleration (or deceleration) has a speed of #1 m/s# at #t=0# and moves a total of 180 m by #t=4#, what was the object's rate of acceleration?

Explanation:
The average speed of the particle over 4 s is
Since for a uniformly moving object the average speed over an interval is the average of the initial and final speeds, the final speed must be
Thus, the acceleration is
