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 = 45 cm
#$&*
• 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 = 3 s
vf = 50 cm/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
v0 = 0 cm/s
a = 20 cm/s^2
#$&*
Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
We can find v_Ave if we have v0 and vf, so we can find v_Ave in the first situation only.
#$&*
• Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
We can find ‘dv using v0 and vf so we can only directly find ‘dv in the first situation when using only the given information.
