3/224 A particle with a mass of 4 kg has a position vector in meters given by r 3ti – 2tj – 3k, where t is the time in seconds. For t = 5 s determine the an- gular momentum of the particle and the moment of all forces on the particle, both about the origin O of coordinates. 3/224 A particle with a mass of 4 kg has a position vector in meters given by r 3ti – 2tj – 3k, where t is the time in seconds.
