$\tiny{cp 3.6.11}$
$\textsf{A shopper in a supermarket pushes a loaded cart with a horizontal force of 10 N.}$
$\textsf{If the cart has a mass of 30 kg,}$
$\textit{a. how far will it move in 3s starting from rest }$
\begin{align*}\displaystyle
ma&=F \\
a&=\frac{F}{m} \\
&=\frac{10N}{30 \, kg} \\
&=.333 \, m/s^2\\
x&=x_o + v_o t+\frac{1}{2}at^2 \\
&=0+0+(.333 \, m/s^2) \cdot (3 s)^2 \\
&\approx \color{red}{3 \, m}
\end{align*}ok I think this is ok
but the notation could be better
so suggestions

Thought Questions:

1) Where did the 1/2 go?
2) Are you SURE the acceleration is constant?
3) No friction at all?
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
