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: ->->->->->->->->->->->-> :

Acceleration=9.76

#$&*

• 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: ->->->->->->->->->->->-> :

Acceleration in the first one is 9.76 and acceleration for this equation is 9.1

#$&*

• Are these observations consistent with the accepted value of the acceleration of gravity, which is 9.8 m / s^2?

answer/question/discussion: ->->->->->->->->->->->-> :

I believe they are relatively consistent within each other, yes.
