The problem:
A ball accelerates at 8 cm/s^2 for 3 seconds, starting with velocity 12 cm/s.
What will be its velocity after the 3 seconds has elapsed?
v = vo + at.
v = 12cm/s + 8cm/s^2*3s
v = 12cm/s + 24cm/s
v = 36cm/s

Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vAve = (36cm/s + 12cm/s)/2 = 24cm/s
#$&*
How far will it travel during this interval?
vAve = ds/dt
ds = vAve*dt
ds = 24cm/s * 3s = 72cm
