Coughing forces the trachea (windpipe) to contract, which in turn affects the velocity of the air through the trachea. the velocity of the air during coughing can be modeled by v = k(r – r)r2, 0 ≤ r < r, where k is a constant, r is the normal radius of the trachea, and r is the radius during coughing. what radius r will produce the maximum air velocity?

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
