Calculate the maximum acceleration (in m/s2) of a car that is heading up a 11° slope (one that makes an angle of 11° 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.

An initially stationary box of sand is to be pulled across a floor by means of a cable in which the tension should not exceed 876 N. The coefficient of static friction between the box and the floor is 0.360. (a) What should be the angle between the cable and the horizontal in order to pull the greatest possible amount of sand, and (b) what is the weight of the sand and box in that situation?

Calculate the maximum deceleration of a car that is heading down a 11.5° slope (one that makes an angle of 11.5° with the horizontal) under the following road conditions. You may assume that the weight of the car is evenly distributed on all four tires and that the static coefficient of friction is involved--that is, the tires are not allowed to slip during the deceleration.
