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