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: ->->->->->->->->->->->-> :
Change in velocity= acceleration * 'dt
= 8 cm/s^2 * (3 sec)= 24 cm/s
Final Velocity= 12 cm/s + 24 cm/s= 36 cm/s
#$&*
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
Average Velocity: (12 cm/s+36 cm/s)/2= 24 cm/s
#$&*
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
'ds=average velocity*time interval
= 24 cm/s * 3 sec= 72cm
