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: ->->->->->->->->->->->-> :
8cm/s^2 * 3s = 24 cm/s
12cm/s + 24m/s = 36cm/s
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vAve = vInitial + vFinal / 2
vAve = (12cm/s + 36cm/s) / 2
vAve = 48cm/s / 2
vAve = 24cm/s
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vAve = ‘ds / ‘dt
24cm/s = ‘ds / 3s
‘ds = 72cm
