A towing machine can deliver horizontal towing force T by a strong, inclastic cable. The towing force T can vary as shown in the graph. A 490 kg timber, initially at rest, is attached to the towing machine. The static friction coefficient between the timber and the surface is Hk = 0.49, and the towing machine must overcome the minimum force needed to move the timber against the static friction. If the kinetic friction coefficient between the timber and the surface is µg = 0.39, determine the velocity of the timber at t= 6.5 seconds. M T (N) 2000 T=125 (s)
