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 will be 36m/s because 8m/s^2*3s=24m/s+12m/s=36m/s

#$&*

• Assuming that acceleration is constant, what will be its average velocity during this interval?

answer/question/discussion: ->->->->->->->->->->->-> :

The average velocity is 24m/s because 36m/s + 12m/s = 48m/s /2 = 24m/s.

• How far will it travel during this interval?

answer/question/discussion: ->->->->->->->->->->->-> :

The ball will travel 72 meters because 24m/s *3s=72m.
