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: ->->->->->->->->->->->-> :
The velocity at 3 seconds is 36 cm/s. I got this by taking vf = v0 + a (t)
This is 12 + 24.

• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
The average velocity is 24 cm/s. You add final to initial velocity and divide by 2.

• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
The distance traveled is 72 cm. I multiplied 24 by the time.
