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: ->->->->->->->->->->->-> :
at an acceleration of 8 cm/s/s for 3 seconds, it will go 24 cm/s. this is added to the intitial 12 cm/s to get 36 cm/s.

• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vf + v0 / 2 so 12 cm/s + 36 cm/s /2 = 24 cm/s
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
24 cm/s * 3 seconds = 72 cm
