$- 48{\rm{\hat k}}$

1.	The time dependence of the position of a particle of mass m = 2 is given by \({\rm{\;}}\left[ {\vec r\;} \right]\left( {\rm{t}} \right) = 2{\rm{t}}\hat i - 3{{\rm{t}}^2}\hat j\). Its angular momentum, with respect to the origin, at time t = 2 is:
A.	\(48\left( {{\rm{\hat i}} + {\rm{\hat j}}} \right)\)
B.	\(36{\rm{\hat k}}\)
C.	\(- 34\left( {{\rm{\hat k}} - {\rm{\hat i}}} \right)\)
D.	\(- 48{\rm{\hat k}}\)
Answer» E.

The time dependence of the position of a particle of mass m = 2 is given by \({\rm{\;}}\left[ {\vec r\;} \right]\left( {\rm{t}} \right) = 2{\rm{t}}\hat i - 3{{\rm{t}}^2}\hat j\). Its angular momentum, with respect to the origin, at time t = 2 is:
