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^2
`dt= 3 sec
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^2

Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
1st situation: yes it is possible to get vAve.
2nd situation: yes it is possible to get vAve
3rd situation: no it is not possible to get vAve from this

• Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
1st situation: yes it is possible to determine `dv
2nd situation: yes it is possible to determine `dv
3rd situation: no it is not possible to determine `dv
