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: ->->->->->->->->->->->-> : v0 = 10 cm/s, vf = 20 cm/s, `ds = 45cm
• 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: ->->->->->->->->->->->-> : a = 10 cm/s^2, `dt = 3s, vf = 50cm/s
• A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> : `ds =30 cm, a= 20 cm/s^2
also v0 = 0
Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> : In the first instance yes, but not in the second one.
• Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> : In the second yes, but not in the first one.
