We know from studying friction forces that static friction increases with increasing normal force between the surfaces, which becomes important for vehicles traveling on icy or snowy roads that have coefficients of static friction much smaller than those of dry pavement. In particular, the greater the normal force on the drive wheels (those coupled to the engine), the better the traction. The horizontal position of the center of mass of a typical compact automobile is located 1.1 m toward the rear as measured from the front wheel axle. The wheelbase (distance from the front wheel axle to the rear wheel axle) is 2.7 m. Assume the car is stationary on level ground and has a weight of 12,000 N. Determine the total normal force on the two front tires and on the two rear tires. Which do you suppose are the drive wheels in this case?
What force must be applied to push a carton weighing 260 N up a 18 degree incline, if the coefficient of kinetic friction is 0.41? Assume the force is applied parallel to the incline and the velocity is constant. (Enter the magnitude of the force.)
A woman pulls a sled which, together with its load, has a mass of m kg. Let g be the acceleration due to gravity. If her arm makes an angle of theta with her body (assumed vertical) and the coefficient of friction (a positive constant) is mu, the least force, F, she must exert to move the sled is given by
A mass of 1.66 kg is released from rest while upon an incline of 34.1 degrees. If the coefficient of kinetic friction regarding the system is known to be 0.463, what amount of time will it take the mass to slide a distance of 2.72 m down the incline?
The 1.5-Mg four-wheel-drive Jeep is used to push two identical crates, each having a mass of 500 kg. If the coefficient of static friction between the tired and the gournd is us=0,6 , determine the maximum possible speed the Jeep can achieve on 5 s without causing the tired to slip. The coefficient of kinetic friction between the crates and the ground is UK=0.3
Calculate the maximum acceleration (in m/s2) of a car that is heading up a 13.5° slope (one that makes an angle of 13.5° with the horizontal) under the following road conditions. Assume that only half the weight of the car is supported by the two drive wheels and that the static coefficient of friction is involved--that is, the tires are not allowed to slip during the acceleration. (a) on dry concrete (b) on wet concrete (c) on ice, assuming that µs = 0.100, the same as for shoes on ice
The floor of a railroad flatcar is loaded with loose crates having a coefficient of static friction of 0.25 with the floor. If the train is initially moving at a speed of 48 km/h, in how short a distance can the train be stopped at constant acceleration without causing the crates to slide over the floor?

Calculate the maximum acceleration of a car that is heading up a 4º slope (one that makes an angle of 4º with the horizontal) under the following road conditions.

(Ignore rolling.) On dry concrete, assuming that ??=1.0.
