• A ball accelerates uniformly from 10 cm/s to 20 cm/s while traveling 45 cm.

answer/question/discussion: ->->->->->->->->->->->-> : Vo= 10, Vf=20, dt=45

• A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.

answer/question/discussion: ->->->->->->->->->->->-> :Vf=50 dt=3

• A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.

answer/question/discussion: ->->->->->->->->->->->-> : Vo=0, dt=30,

Then for each situation answer the following:

• Is it possible from this information to directly determine vAve?

answer/question/discussion: ->->->->->->->->->->->-> :1 yes, 2 no, 3 yes,

• Is it possible to directly determine `dv?

answer/question/discussion: ->->->->->->->->->->->-> :1 yes, 2 no, 3 yes
