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: ->->->->->->->->->->->-> :
8cm/s*3s=24cm/s+12cm/s=36cm/s
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
12cm/s+36cm/s=48cm/s/2=24cm/s
@&
12cm/s+36cm/s=48cm/s
12cm/s+36cm/s = 48cm/s/2 is a false statement.
48cm/s/2=24cm/s, and this is the average of the initial and final velocities. Since acceleration is constant this is also the average velocity.

• How far will it travel during this interval?

24cm/s*3s=72
