Best ResponseYou've already chosen the best response.1That's true but it only helps if you know one of those equations. The position function is: \[x _{0}+(dx/dt)t+(1/2)(d ^{2}x/dt ^{2})t ^{2}\] Or as you probably like to remember it: \[x _{0}+vt+\frac{ at ^{2} }{ 2 }\]

Best ResponseYou've already chosen the best response.1But do keep in mind what you said too. It saves you the trouble of blindly memorizing three equations, and so you only need one of them to get the other two.

Best ResponseYou've already chosen the best response.1Do you know what to do now? Because from here you just need to plug it in

Best ResponseYou've already chosen the best response.1x0 is the initial position. v is the initial velocity (in retrospect I forgot to write v0 to be consistent). a is the acceleration. And t is time.

Best ResponseYou've already chosen the best response.1I think you just need to set up the equation and leave t as is

Best ResponseYou've already chosen the best response.0would it be 10+ (20)=40(t)^2/2?
