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
24 cm/s + 12 cm/s = 36 cm/s
#$&*
Assuming that acceleration is constant, what will be its
average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
12 cm/s + 36 cm/s = 48 cm/s
48 cm/s / 2 = 24 cm/s
#$&*
How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
change in position = vAve * t
24 cm/s * 3 s = 72 cm
