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 = 10 cm/s
vf = 20 cm/s
'dt = 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: ->->->->->->->->->->->-> :
a = 10 cm/s^2
'dt = 3 s
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: ->->->->->->->->->->->-> :
'ds = 30 cm
v0 = 0 cm/s
a = 20 cm/s^2

Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
For question 1, yes it is possible to directly determine vAve. vAve = (vf + v0) / 2
For question 2, it is not directly possible to determine vAve, however, i can be found. You can solve for v0 using a = (vf - v0) / 'dt, and then use vAve = (vf + v0) / 2.
For question 3, no it is not possible to directly determine vAve because there is no time interval given.

• Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
For question1, yes it is possible to directly solve 'dv.
For questions 2 and 3, no direct determination of 'dv with the data given.
