$11\mathrm{.}37-$ Angular Momentum

Puntos:$2$

A particle of mass $2\mathrm{.}5$ kg has position vector $[\frac{r}{\frac{?}{?}}$vec$]=(3\mathrm{.}0{[}^{{?}^{?}}(i)]-3\mathrm{.}0{[}^{{?}^{?}}(j)])m$ at a particular instant of time when its velocity is $2\frac{m}{s}$ with respect to the origin. What is the angular momentum of the particle?

$37\mathrm{.}5k{g}^{**}\frac{m^2}{s}$

$[^($i$)][^($j$)]$

If a force $[\frac{F}{\frac{?}{?}}$vec$]=(+5\mathrm{.}0{[}^{{?}^{?}}(j)])N$ acts on the particle at this instant, what is the torque about the origin?
