A particle with a mass of 4 kg has a position vectorin meters given by r = 3t2i 2tj 3k
Chapter 3, Problem 3/224(choose chapter or problem)
A particle with a mass of 4 kg has a position vector in meters given by \(\mathbf{r}=3 t^{2} \mathbf{i}-2 t \mathbf{j}-3 \mathbf{k}\), where t is the time in seconds. For t = 5 s determine the angular momentum of the particle and the moment of all forces on the particle, both about the origin O of coordinates.
