Part A

A small $13\mathrm{.}0g$ bug stands at one end of a thin

uniform bar that is initially at rest on a smooth

horizontal table. The other end of the bar pivots

about a nail driven into the table and can rotate

freely, without friction. The bar has mass $70\mathrm{.}0g$

and is $120cm$ in length. The bug jumps off in the

horizontal direction, perpendicular to the bar, with a

speed of $25\mathrm{.}0c\frac{m}{s}$ relative to the table.
