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: ->->->->->->->->->->->-> :
'dv = a * 'dt
'dv = 8 * 3 = 24cm/s
vf = v0 + 'dt
vf = 12 + 24 - 36cm/s
#$&*
Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
The average velocity is: vave = (12+36)/2 = 24 cm/s
#$&*
How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
'ds = vave * 'dt
'dst = 24 * 3 = 72 cm
