The problem:
A ball accelerates at 8 cm/s^2 for 3 seconds, starting with velocity 12 cm/s.
What will be its velocity after the 3 seconds has elapsed?
answer/question/discussion: ->->->->->->->->->->->-> :
aAve = (v_f - v_0) / `dt = 8 = (v_f - 12) / 3
v_f - 12 = 24
v_f = 36 m/s
#$&*
Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vAve = (v_f + v_0) / 2 = (36 + 12) / 2 = 24 m/s
#$&*
How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
`ds = vAve * `dt = 24 m/s * 3 s = 72 m
