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: ->->->->->->->->->->->-> :
aAve=9.78m/s^2
#$&*
Is this consistent with an observation which concludes that a ball dropped from a height of 5 meters reaches the ground in 1.05 seconds?
answer/question/discussion: ->->->->->->->->->->->-> :
No, the aAve of a ball dropped from a height of 5m that reaches the ground in 1.05 seconds is about 8.50m/s^2. While it is relatively close to the accepted value of the acceleration of gravity it is not as close as the preceding problem.
#$&*
Are these observations consistent with the accepted value of the acceleration of gravity, which is 9.8 m / s^2?
answer/question/discussion: ->->->->->->->->->->->-> :
The first problem is more consistent with the accepted value of the acceleration of gravity.
