Hi I am trying to help a family member who has been asked to..


Make a the subject of the equation s=ut x 1/2at*2 (newton equation)

(sorry but I couldn't get the correct characters to depict squared or half and I hope this hinders nobody :D )

I have tried to do it but I doesn't work out when I assign set values to it.

Any help would be greatly appreciated


Thanks
Rudey

Is this what you mean?

s=ut\cdot\frac{1}{2}at^{2}?

It should be s = ut + \frac{1}{2}at^2 Maybe this is where you are going wrong :) It's a suvat equation, not a newton equation.

right so the original equation looks correct. How do you make a the subject...

No, it's s = ut + \frac{1}{2}at^2
