Atruck traveling at 75 mi/h has a braking efficiency of 70%. the coefficient of road adhesion is 0.80. ignoring aerodynamic resistance, determine the theoretical stopping distance on a level grade.

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively
