A ball falls freely from rest at a height of 2 meters. Observations indicate that the ball reaches the ground in .64 seconds.
• Based on this information what is its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
.64 sec x 2 meters = 1.28 cm/sec
@& This is not how you find acceleration.
What is the definition of accleration and how does your calculation differ from that definition?
What can you find from `ds = 2 meters and `dt = .64 seconds?*@

• Is this consistent with an observation which concludes that a ball dropped from a height of 5 meters reaches the ground in 1.05 seconds?
answer/question/discussion: ->->->->->->->->->->->-> :
No
@& You need to show your reasoning.
'yes' and 'no' answers must always be accompanied by detailed justification.*@
#$&*
• Are these observations consistent with the accepted value of the acceleration of gravity, which is 9.8 m / s^2?
answer/question/discussion: ->->->->->->->->->->->-> :
Yes
