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: ->->->->->->->->->->->-> :
If the ball accelerates for 3 seconds the total acceleration will be 8cm/s^s*3s=24cm/s
Add this to the v0 of 12cm/s gives us 36cm/s vf
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
vAve = (vf+v0)/2=(12+36)/2=48cm/s/2 = 24cm/s
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
`ds = 24cm/s *3s = 72cm
