Here's the code. (I put the line for v in bold.)
Code: Select all
\begin{tikzpicture}
\draw (4.7,4.7) -- (0,0) -- (5,0) --(5,4.41);
\coordinate [label={$\theta$}] (t) at (0.8, 0.1);
\draw (2,2) -- (1, 3) -- (3, 5) -- (4,4);
\draw node at (2.5, 3.5) {$M$};
[b] \draw [->] (2,5) edge node[above left] {v} (3,6);[/b]
\fill [black] (9,3) circle(2pt);
\coordinate [label={M FBD}] (MFBD) at (8,5);
\path [->] (9,3) edge node[right] {Mg} (9,0);
\path [->] (9,3) edge node[above right] {N} (7.5,4.5);
\path [->] (9,3) edge node[above left] {f} (8.29,2.39);
\path [->] (9,3) edge node[above left] {T} (10.41,4.41);
\fill [black] (13,3) circle(2pt);
