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?

answer/question/discussion: ->->->->->->->->->->->-> :

vf = v0 + (a * 'dt). 12cm/s + (8cm/s^2 * 3s) = 36cm/s.

#$&*

Assuming that acceleration is constant, what will be its average velocity during this interval?

answer/question/discussion: ->->->->->->->->->->->-> :

(v0+vf)/2 = (36 + 12m/s)/2 = 24m/s.

#$&*

How far will it travel during this interval?

answer/question/discussion: ->->->->->->->->->->->-> :

'ds = vAve * 'dt = 24m/s * 3 = 72m.
