Thoughts: F = ma. Would the acceleration be g? You would divide the weight by g to get the mass of the stone, correct?

**drwls**, Friday, December 14, 2007 at 6:46pmThe acceleration a is given by

a = F/m = 12.30 m/s^2

The velocity when released is

V = sqrt (2aX) = 7.68 m/s

The height H that it reaches after that is given by

gH = V^2/2

H = V^2/(2g)
