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
#$&*
• A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> :
a= 10cm/s/s
`dt= 3seconds
vf=50cm/s
#$&*
• 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/s

@&
Also, since the ball starts from rest, you know that v_0 = 0.

Then for each situation answer the following:
• Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
1. yes, Vave= (vf+vo)/2
2. no
3. no
#$&*
• Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
1. no
2. yes
3. no
