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:
12cm/s+(8cm/s^2*3s)=36cm/s
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion:
(12cm/s+36cm/s)/2=24cm/s
• How far will it travel during this interval?
answer/question/discussion:
24cm/s*3s=72cm
