[1 point, 10 tries] What is the magnitude of the angular momentum of a 298.0 g particle travelling 3.92 m/s at position ( x,y )=(1.27 m, 2.39 m)? Answer: 2.79e+00 kg*m^2/s 2 . [1 point, 10 tries] Given M =6.89 i +2.22 j -1.24 k and N =1.57 i -1.09 j -3.30 k , calculate the vector product M × N . Enter in the order xyz or ijk . Answer: -8.68E+00 2.08E+01 -1.10E+01 3 . [1 point, 10 tries] A 1.62 kg particle moves in the xy plane with a velocity of v =(4.16 i -3.38 j ) m/s. Determine the magnitude of the particle's angular momentum about the origin when its position vector is r = (1.44 i +2.42 j ) m. Answer: 2.42E+01 kg*m^2/s 4 . [1 point, 10 tries] The position vector of a particle of mass 2.26 kg is given as a function of time by r =(5.85 i +4.34 t j ) m. Determine the magnitude of the angular momentum of the particle about the origin. Answer: 5.74E+01 kg*m^2/s Go to problem [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] 1-18 Status: Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y
