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: ->->->->->->->->->->->-> :
'dv = aAve * 'dt = 8 * 3 = 24 cm/s
vf = 24 cm/s + 12 cm/s = 36 cm/s
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vAve = (36 cm/s + 12 cm/s) / 2 = 24 cm/s
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
'ds = vAve * 'dt = 24 cm/s * 3 = 72 cm
#$&*
