a. Multiply both sides by 2. Divide both sides by

b. Multiply both sides by 2. Divide both sides by . Take the square root of both sides, but discard the negative root. (negative time is meaningless).

c. Multiply both sides by 2. Divide both sides by . Then sit back and ponder what a ridiculous lot of foolishness you just went through just to find the value of a constant -- and a small integer at that.

Using the equation 2d=%28at%5E2%29
a.solve for a
d=%28at%5E2%29%2F2
2d=%28at%5E2%29
2d%28t%5E2%29=a
====================
b.solve for t
2d=%28at%5E2%29
t%5E2+=+2d%2Fa
t+=+sqrt%282d%2Fa%29
------------------------
c.solve for 2
2 = 2
