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: ->->->->->->->->->->->-> :
36 cm/s
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
24 cm/s
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
8 cm
traveling at an average of 24 cm every second, the ball will travel further than 8 cm in 3 seconds.

You're doing well with acceleration and slope, but having some issues with displacement and area. I don't think you'll have much trouble resolving them, but you should submit a revision on this one so we can be sure.
