anonymous · Answer

did you try $$x=x_{0}+v _{0}t+\frac{ 1 }{ 2 }at ^{2}$$ ?

anonymous · Answer

this will help you to find the acceleratio, cause you have the other stuff already.

anonymous · Answer

No, I didn't. I tried the following formula:|dw:1351993517071:dw|

anonymous · Answer

would these work too? I'm not familiar with the formula you provided.

anonymous · Answer

s=ut+1/2at^2
