A 5-foot-tall person is walking towards a 7-foot-tall lamppost at a uniform rate of 2 feet per second. Find how fast the subtended angle of the lamppost from the person is increasing when the person is horizontally 1 foot from the lamppost. Assume the eye level of the person to be also 5 feet for simpler analysis. O 1 rad/s 77 rad/s 65 22 rad/s 19 33 rad/s 29 O o o
