**drwls**, Wednesday, June 22, 2011 at 12:05amRequire the following:

(g/2)T^2 = 480

(g/2)(T-1)^2 + V*(T-1) = 480

You have two equations in two unknowns (V and T) and can solve for V.

The first equation tells you that stone A requires

T = 9.8 seconds to fall to the ground. (if g= 10)

Use that value of T in the second equation to solve for V.
