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 cm/s^2 * (3 sec) = 24 cm/s velocity change in three seconds. 24 cm/s + 12 cm/s = 36 cm/s = velocity after 3 seconds has elapsed.
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: vAve = (12 cm/s + 36 cm/s) / 2 = 24 cm/s.
• How far will it travel during this interval?
answer/question/discussion: it will travel at 24 cm/s for 3 seconds, finishing up (24*3) 72 cm farther.
