Askier of mass 103 kg comes down a slope of constant angle 21◦ with the horizontal.
what is the force on the skier parallel to the slope? neglect friction. the acceleration
of gravity is 9.8m/s . answer in units of n.

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
