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: ->->->->->->->->->->->-> :
Bf=vi+at
12cm/s+8(3)= 36cm/s
Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
36cm/s+12cm/s/2=24cm
How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
24(3)= 72 meters
24 is the average and since the acceleration is constant it is still at 3 seconds.
