Acar slows down -27.7 m/s to -10.9 m/s "while" undergoing a displacement of -105 m what was its acceleration

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

An object has a weight of 500 on earth what is the mass of this object

=force × distance a. work b. velocity c. pressure d. momentum
