SUMMARY
The sled's acceleration was calculated to be 13.8889 ft/s² based on the distances covered at specific time intervals. The sled starts from rest and travels 80 ft in the first 2 seconds, then 125 ft in the next 2 seconds, and finally 180 ft in the subsequent 2 seconds. The assumption of "without constant acceleration" was clarified to mean "with constant acceleration" for the purpose of solving the problem. The equations used to derive the acceleration were based on the kinematic equation s = ut + ½at².
