13. A force, F = [12, 15, 47]N is applied over a distance of d = [125, 85, 147]m. Determine the amount of work, measured in Joules, done in this situation. [3] 14. Find the magnitude of the torque vector, measured in Newton-meters, produced by a cyclist exerting a force of F = [60, 15, 105]N on the shaft-petal r = [10, 13, 50]cm long. Recall: 7 = 7 X F [4]
