A 160 lb person is being pulled on a tube in the snow by a four wheeler when the four wheeler starts to spin at 3 rad/s. Initially, the person on the tube is 12 feet from the center of rotation when the towing rope gets wrapped around the axle and begins to pull in at 3 ft/s. Determine the velocity of the person and the tube when they are 4 feet from the center of rotation. Neglect the mass of the four wheeler, tube, and towing rope. Assume the tube is on a smooth surface and that angular momentum is conserved. (108.0 ft/s)

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.
