Small block is given an initial velocity measured along the horizontal floor of an elevator moving with a constant downward acceleration. Friction causes the block to move a distance S measured along the floor before it stopping. Experiment repeats with the same initial velocity (magnitude and direction) relative to the floor when the elevator has an upward acceleration of the same magnitude a, and the block slides a shorter distance s2. Determine the elevator acceleration a. Test your result for s = 1.3 m, s2 = 1 m, uk =0.5.Hint: The accelerations ax are not the same in the two experiments, only ay = a are the same.
