-> 13. A force of F = [3,5,12], in Newtons, is applied to lift a box, with displacement s = [2,1,6]. Calculate the work against gravity and compare it to the work in the direction of travel. [3] [4] 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 = [10, 13, 50] cm long. Recall: r=rx F Page 12 of 13
