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 = 10cm/s
vf = 20cm/s
`ds = 45cm
#$&*
A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> scussion:
a = 10 cm/s^2
`dt = 3s
vf=50 cm/s
#$&*
A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> scussion:
v0 = 0cm/s
`ds = 30cm
a = 20 cm/s^2
#$&*
Then for each situation answer the following:
Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
It is possible to directly determine vAve from the first situtation vAve=(v0+vf)/2
Is is not directly possible from the other two, you would need multiple steps
#$&*
Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
It is possible to directly determine `dv from the first situtation `dv =vf-v0
Is is not directly possible from the other two, you would need multiple steps
