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