\begin{problem*}{5.63}
A crate of wieght $F_g$ is pushed by a force $\vect{P}$ on a
-horizontal floor as shown in Figure P5.63. The coefficient of static
+horizontal floor as shown in Figure~P5.63. The coefficient of static
friction is $\mu_s$, and $\vect{P}$ is directed at an angle $\theta$
below the horizontal. \Part{a} Show that the minimum value of $P$
that will move the crate is given by
