If I hit a swinging $${\mathtt{10}}$$ pound bag of sand $${\mathtt{37}}$$ inches in $${\frac{{\mathtt{1}}}{{\mathtt{3}}}}$$ of a second, what force did I apply to that swinging $${\mathtt{10}}$$ pound bag of sand? Show how to get to the answer.

**Yes, very cute Nauseated.** (ノ◒▽◒)ノ

I knew the units would not be the standard ones but I didn't think it would matter.

I think i have worked out what you were talking about.

it was just a trivial copy error that left the answer with the wrong units.

I am sure Nauseated could have fixed it but he is too busy in Wonderland.

He has to keep his like-minded friend - the hatter, company.

Half joking Nauseated.

We all have to get our priorities right. :)

Anyway maybe my answer is fixed now. |ʘ‿ʘ)╯

Hi Gibson,

You probably already know that I am not a physics person but I will give it a shot :)

I have not taken the swinging bit into any consideration. I don't think that you can because you do not know what its 'radius' is.

F=ma m=10 pounds

s=37 inches, t=1/3 sec, u=0, v=? a=? But I need to find a

So if I am to use physics formulas then it could have s,t,u and a BUT not v

$${\mathtt{S}} = {\mathtt{ut}}{\mathtt{\,\small\textbf+\,}}\left({\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right){\mathtt{\,\times\,}}{{\mathtt{at}}}^{{\mathtt{2}}}$$

$$\\37=0t+\frac{1}{2}a\left(\frac{1}{3}\right)^2\\\\

37=\frac{1}{2}*a*\frac{1}{9}\\\\

37*2*9=a\\\\

a=666\;inches/s^2\\\\\\

F=ma\\\\

F=10*666\\\\

F=6660\;pounds\;inches/s^2\\\\

F=6660/12\;pounds\;feet/s^2\\\\

F=555\;pounds\;feet/s^2\\\\$$

NOTE: A small error has been fixed. Maybe it is right now.
