air track gizmo answer key
0 m/s and the cart accelerated uniformly over 4 seconds, what was the acceleration? Answer: Since velocity changes from 0 to 2 m/s over 4 seconds, \(a = \Delta v / \Delta t = 2\, m/s / 4\, s = 0.5\, m/s^2\). Key Point: The answer key illustrates the use of kinematic equations and
