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: ->->->->->->->->->->->-> :
8= (vF-12)/3
24=vF-12
vF= 36cm/s
since we know acceleration, initial velocity and time interval we can solve for final velocity.
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
(36cm/s+12cm/s)/2= 24cm/s
(vf+v0)/2
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
24cm/s * 3sec= 72 cm
