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 * 3sec=24cm/s/s +12cm/sec= 36cm/sec
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
36cm/s +12cm/sec=48cm/sec 48cm/sec/2= 24cm/sec
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
24cm/sec *3sec= 72cm
#$&*
