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
‘ds=45 cm
‘dt=?
A=?
#$&*
• A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> :
v0=?
vf=50 cm/s
‘ds=?
‘dt=3 s
A=10 cm/s^2
#$&*
• A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> :
v0=0cm/s
vf=?
‘ds=30 cm
‘dt=?
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: ->->->->->->->->->->->-> :
Situation 1. Yes we have both initial and final velocity
Situation 2. No we would need to determine initial velocity first.
Situation 3. No we would need to determine final velocity first.

• Is it possible to directly determine `dv?

Situation 1. Yes we have both initial and final velocity
Situation 2. No we would need to determine initial velocity first.
Situation 3. No we would need to determine final velocity first.
