2. A firefighter feels the hose pushing backwards onto him as he uses it to put out a fire. What is the most likely
cause of this?
A. The hose material is very elastic.
B. Since the hose is at rest, it tends to stay at rest.
C. The force exerted on the water equals the mass of the water times its acceleration
D. The escaping water exerts an equal and opposite force on the hose.

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
