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=30
a= 20cm/s/s
@&
The ball starts from rest so its initial velocity is v0 = 0.

Then for each situation answer the following:
Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
situation one: yes
situation two: yes
situation three: no
#$&*
Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
situation one:yes
situation two: yes
situation three:no
