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: avg accel= change in vel/time
Change in vel = avg accel * time
Change in vel = 8cm/s^2 * 3 sec
Change in vel = 24cm/s
Final Velocity = 24cm/sec + 12cm/sec = 36cm/sec
Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: 36cm/s + 12 cm/s = 48cm/sec
Avg velocity = (vf + vo)/2
Avg velocity = 48/2 = 24cm/sec
How far will it travel during this interval?
answer/question/discussion: vAve = change in position / time
Change in position = vAve * time
Change in position = 24cm/sec * 3 = 72 cm
