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: ->->->->->->->->->->->-> :
The acceleration due to gravity is (g) = 9.8 m / s^2.
#$&*
@& That result is not obtained from the given information. The question is
'Based on this information what is its acceleration?'
Your answer is based on the accepted value of the acceleration of gravity at the surface of the Earth. Your result should be compared to this, but is completely independent of the accepted value.*@
• Is this consistent with an observation which concludes that a ball dropped from a height of 5 meters reaches the ground in 1.05 seconds?
answer/question/discussion: ->->->->->->->->->->->-> :
Yes, this will be consistent with the observation.
#$&*
@& You have to use the given information to obtain a value.*@
• Are these observations consistent with the accepted value of the acceleration of gravity, which is 9.8 m / s^2?
answer/question/discussion: ->->->->->->->->->->->-> :
Yes, because the acceleration for falling objects is the same = 9.8 m / s^2.
