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 = 9.77 m/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 it is not. If the ball is dropped at v0 = 0m/s, ‘ds = 5meters, and ‘dt = 1.05 meters, the acceleration would then be about 9.07m/s^2

•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 observation is consistent with the accepted value of acceleration of gravity.
