You are looking up and tracking a bird's steady horizontal motion. The bird is 35 m 35m above the ground and moving at 6 m / s 6m/s. Write an expression for the angle of your head as a function of time ( t). Assume the bird is directly overhead at = 0 t=0. Write the expression for the angle of your gaze from the vertical, so that zero radians (or degrees) represents looking straight up, and 2 2 radians ( 90 deg 90deg) is looking horizontal. Please denote multiplication with *. If you need to use any inverse trig functions please use asin, acos, atan
