For each situation state which of the five quantities v0, vf, `ds, `dt and a are given, and give the value of each.
• A ball accelerates uniformly from 10 cm/s to 20 cm/s while traveling 45 cm.
answer/question/discussion: ->->->->->->->->->->->-> : The quantities that are given are v0, vf, and ‘ds.
• 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: ->->->->->->->->->->->-> : The quantities that are given are a, ‘dt, and vf.
• A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> : The quantities that are given are ‘ds, v0, and a.
Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> : First situation = yes; Second situation = no; third situation = no.
• Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> : Yes, yes, and yes.
