3) The log has a mass of 500 kg and rests on the ground for which the coefficients of static and kinetic friction are T(N) H, = 0.5 and Hg = 0.4, respectively. The winch delivers a horizontal towing force T to its cable at A which varies as 1800 T= 200 shown in the graph. Determine the speed of the log when t = 5 s. Originally the tension in the cable is zero. Hint: First determine the force needed to begin moving the log. - (s) Partial Ans. t = 2.476 s to get moving, v = 7.65 m/s
