What are the average acceleration and final velocity of an object which accelerates uniformly from rest, attaining a velocity of 40 cm/sec in 13.6 seconds? How far does the object travel during the 13.6 seconds?vF = 40cm/sec

average acceleration = vF / `dt = 40cm/sec / 13.6sec = 2.94cm/s/s

`ds = vAve * `dt = 20cm/sec * 13.6sec = 272cm"
