Question
Calculate the maximum deceleration (in m/s?) of a car that is heading down a 10.5° slope (one that makes an angle of 10.5° 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.
