Re: OT: Looking for a good physics site
Could someone tell me why '1/2 * 5 * 3^2 - 117.5 + 50 = 45?' returned -45? Thanks. I can't see the error.
(1/2) * A * T^2 + V * T + P = D
A = 5
T = 3
P = 50
V = 15
D = 117.5
(1/2) * A * T^2 + V * T - D = P
(1/2) * 5 * 3^2 + 15 * 3 - 117.5 = 50?
2.5 * 9 + 45 - 117.5 = 50?
22.5 + 45 - 117.5 = 50? // Don't think so...
-50 != 50
Um...Where, exactly, did I make a mistake?
