A child has a spherical helium balloon tied to her wrist as she walks through the park at a constant speed of 0.46 m/s in the +ŷ-direction. The balloon has a diameter of 7 cm, and it is tied to a 1 m long string.Take the density of air to be 1.108 kg/m³, the density of helium to be 0.122 kg/m³, and the density of the latex of the balloon to be 0.013 kg/m². The viscous drag constant of the balloon is 0.00148 kg/s.What is the direction of the string from the girl's wrist to the balloon?û =xŷ +X 2

While workers spray paint the ceiling of a room, numerous small paint aerosols are dispersed into the air. Eventually, these particles will settle out and fall to the floor or other surfaces. Consider small spherical paint particles of diameter D = 10 μm and specific gravity of 1.2. Determine the time it would take this particle to fall 2.4 m from near the ceiling to the floor. Assume that the air within the room is motionless.

When a foreign object that is lodged in the trachea (windpipe) forces a person to cough, the diaphragm thrusts upward, causing an increase in pressure in the lungs. At the same time, the trachea contracts, causing the expelled air to move faster and increasing the pressure on the foreign object. According to a mathematical model of coughing, the velocity v (in cm/s) of the airstream through an average-sized person's trachea is related to the radius r of the trachea (in cm) by the function v(r) = 3.2(1 − r)r2 1 2 ≤ r ≤ 1. Determine the value of r for which v is a maximum. (Round your answers to two decimal places.)
