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: ->->->->->->->->->->->-> :
8 cm/s/s = ( Vf - 12 cm/s ) / 3 s
24 cm/s = Vf - 12 cm/s
36 cm/s = Velocity final
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
( 36 cm/s + 12 cm/s ) / 2 = 24 cm/s = vAve
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vAve = change in position / change in time
24 cm/s = `ds / 3 s
72 cm = change in distance
