A ball accelerates uniformly as it rolls 20 cm down a ramp, starting
from rest, in 2 seconds.
• What are its average velocity, final velocity and acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
average velocity = 20/2=10 cm/s
final velocity = 10*2= 20 cm/s
acceleration = 20/2= 10 cm/s^2
• If the time interval is in error so that it is 3% longer than the
actual time interval, then what are the actual values of the final
velocity and acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
average velocity = 10-.3= 9.7 cm/s
final velocity = 20-.3 = 19.4 cm/s
acceleration = 10-.3 = 9.4 cm/s^2
• What is the percent error in each?
answer/question/discussion: ->->->->->->->->->->->-> :
average velocity = 3%
final velocity = 6%
acceleration = 6%
