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
#$&*
• A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> :
a = 10cm/s^2 ; `dt = 3s ; vf = 50cm/s
#$&*
• A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> :
`ds = 30cm ; v0 = 0mc/s ; a = 20cm/s^2
#$&*
Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
It is possible to directly determine vAve in 1 but could only be determined after finding other values in 2 and 3.

• Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
It is possible to directly determine `dv in 1 and 2 but could only be determined after finding other values in 3.
