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: ->->->->->->->->->->->-> :
v_0 = 10 cm / s
v_f = 20 cm / s
`ds = 45 cm
#$&*
A ball accelerates uniformly at 10 cm/s^2 for 3 seconds, and at the end of this interval is moving at 50 cm/s.
answer/question/discussion: ->->->->->->->->->->->-> :
a = 10 cm / s^2
`dt = 3 s
v_f = 50 cm / s
#$&*
A ball travels 30 cm along an incline, starting from rest, while accelerating at 20 cm/s^2.
answer/question/discussion: ->->->->->->->->->->->-> :
`ds = 30 cm
v_0 = 0
a = 20 cm / s^2
#$&*
Then for each situation answer the following:
Is it possible from this information to directly determine vAve?
answer/question/discussion: ->->->->->->->->->->->-> :
situation 1: Yes, vAve = (v_f + v_0) / 2 = 15 cm/s
2:No
3:No
#$&*
Is it possible to directly determine `dv?
answer/question/discussion: ->->->->->->->->->->->-> :
Situation 1:Yes, `dv = (v_f - v_0) = 10 cm/s
2:Yes, `dv = a * `dt = 30 cm/s
3:No
