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