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: ->->->->->->->->->->->-> scussion:
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: ->->->->->->->->->->->-> scussion:
a= 10 cm/s/s
`dt= 3 seconds
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: ->->->->->->->->->->->-> scussion:
v0= 0
‘ds= 30
a= 20 cm/s/s
#$&*
Then for each situation answer the following:
*
Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
In all three cases, I feel like I have enough information to do so, but for some reason feel like I can’t put it all together. I’ll look at these farther and get back to you. :)

*
Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
In the first and third cases, yes. It is + 10 cm/s and in the third I believe it to be + 30 cm/s.
