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 = 10cm/s
vf = 20cm/s
‘ds = 45cm
#$&*
A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> :
a = 10cm/s/s
‘dt = 3s
vf = 50cm/s
#$&*
A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> :
‘ds= 30cm
a = 20cm/s/s
@&
The ball starts from rest, so you also know that v0 = 0.

Then for each situation answer the following:
Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
yes
@&
The question indicated 'for each situation'.
There are three situations so this question would require three answers, one for each.
The answers won't be the same for all three.
Note that a simple 'yes' or 'no' is not sufficient. Every 'yes' or 'no' answer must be justified.

Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
yes
@&
See my note on the preceding.

Good job identifying your quantities.
The last couple of questions, though, need to be revised.
