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: ->->->->->->->->->->->-> scussion:
V0 =10 cm/s vf = 20 cm/s ds = 45 cm a = 3.3 cm/s^2
#$&*
*
A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> scussion:
dt = 3 seconds vf = 50 cm/s v0 = 20 cm/s a = 10 cm/s^2 ds = 105 cm
#$&*
*
A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> scussion:
ds = 30 cm a = 20 cm/s^2
also v0 = 0
#$&*
Then for each situation answer the following:
*
Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
Yes it is possible.
#$&*
*
Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
It is also possible.
