Fig. 4
Fig. 4 shows the log has a mass of 800 kg and rests on the ground for which the coefficients
of statics and kinetic friction are µ, = 0.1 and Hx = 0.01, respectively. The motor delivers
a horizontal towing force T to its cable at A which varies as a linear function for t 2 3s and
T = 0.5t? for t < 3s as shown in the graph. Originally the tension in the cable is zero.
a. Determine the time at which the log starts to move.
