A towing machine can deliver horizontal towing force T by a strong, inelastic cable. Thetowing force T can vary as shown in the graph. A 490 kg timber, initially at rest, is attachedto the towing machine. The static friction coefficient between the timber and the surface isHk=0.49, and the towing machine must overcome the minimum force needed to move thetimber against the static friction. If the kinetic friction coefficient between the timber and thesurface is u = 0.39, determine the velocity of the timber at t 6.5 seconds.%3DMT (N)2000T=125r(s)4.

A bicycle and rider, travelling at 12 km/hr on a level road, have a mass of 105 kg. A brake is applied to the rear wheel, which is 800 mm in diameter. The pressure force on the brake is 80 N and the coefficient of friction is 0.06. Find the distance covered by the bicycle and the number of turns of its wheel before coming to rest.
2) After playing a game of pinball, you decide to do some calculations on the launching mechanism. The pinball and the plunger have a mass of 0.30 kg and 0.50 kg respectively. The spring coefficient in the pinball machine is 300 N/m. The original length of the spring is 100 mm and the compressed length is 35 mm. If the coefficient of friction between the ball and the surface is 0.15, calculate the velocity of the ball right before it loses contact with the plunger (in m/s). Note that the plunger is never in contact with the ground and assume the ball slides without rolling. [Ans. to check: 1.23 m/s] HO www
