[1 point, 10 tries] Consider a conical pendulum with an 89.6 kg bob on a 11.4 m wire making an angle of θ =5.65° with the vertical, as seen in the figure below. Determine the horizontal and vertical components of the force exerted by the wire on the pendulum. Enter the horizontal component first and then the vertical component. Answer: 8.70E+01 N 8.79E+02 N 2 . [1 point, 10 tries] Calculate the radial acceleration of the bob. Answer: 9.71E-01 m/s^2 3 . [1 point, 10 tries] A 0.495 kg object is swung in a vertical circular path on a string 0.590 m long. If its speed is 4.44 m/s at the top of the circle, what is the tension in the string there? Answer: 1.17E+01 N Go to problem [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] 1-23 Status: Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y
