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=45 cm
From v0 and vf, since accel is uniform you can easily find vAve.
You can determine `dv from v0 and vf and use the definition of acceleration, along with `dt, to find a.

•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^2, ‘dt=3sec, vf=50cm/s
From a and `dt you can find `dv.
From vf and `dv you can find v0.
From v0 and vf you can find vAve, then`dt allows you to find `ds.

•A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> :
v0=0, a= 20cm/s^2, ds=30cm
From this information, it is not possible to find other information.

Then for each situation answer the following:
•Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
In the first situation you can directly determine vAve .
In the second situation you can't directly determine vAve .
In the third situation you can't get determine anything more than what is given.
#$&*
•Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
In the first situation you can directly determine `dv.
In the second situation you can directly determine `dv.
In the third situation you can't get determine anything more than what is given.
