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: ->->->->->->->->->->->-> :
Ds = .5(a) x dt^2
2 = .5(a) x .64^2
2 = .2(a)
A = 10 m/s/s

• 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: ->->->->->->->->->->->-> :
5 = .5(a) x 1.05^2
5 = .55125 (a)
A = 9.07 m/s/s
