Determine the following quantities for a car driving on a level surface with a coefficient of static friction of 0.75 (¾) and a coefficient of kinetic friction of 0.67 (⅔).

  1. Determine the car's maximum starting acceleration with and without "burning rubber". How do these two methods of starting a car compare?
  2. Determine the car's minimum braking distance with normal brakes and antilock brakes as a function of initial speed. How do these two methods of stopping a car compare?

Under normal driving conditions, car tires can generate a fiction coefficient of approximately 0.7. Antilock braking systems can increase the effective coefficient of friction to as high as 1.0. For car traveling 65 miles an hour, determine the stopping distance for coefficients of friction of 0.7 and 1.0. How much more time do antilock brakes give the driver to respond. Also, why have antilock brakes not produced reductions in crash rates that were anticipated from this calculation?

A mass of 5 kg is placed on a horizontal surface with a coefficient of kinetic friction of 0.4. A force is applied vertically downward to it and another force of 81 Newtons is applied at 14 degrees below the horizontal. As it moves 5 meters in the +x direction it loses 180 Joules of kinetic energy. What is the amount of the force which is applied downward in Newtons?
