In order to get a 15kg object moving to the west, a force of just more than 25 N must be exerted. Once it is moving, however, a force of only 20 N accelerates the object at 0.1 m/s2 to the west. What if the force that static friction can exert on the object? What is the force of kinetic friction?

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
