Question

Canada geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. One goose is flying at 100 km/h relative to the air but a 42 km/h wind is blowing from west to east. a) At what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground? b) How long will it take the goose to cover a ground distance of 550 km from north to south? (Note: Even on cloudy nights, many birds can navigate using the earth's magnetic field to fix the north-south direction.)

Step 1

Given: Velocity of goose relative to air (v_g) = 100 km/h Velocity of wind (v_w) = 42 km/h Using trigonometry: sin(theta) = v_w / v_g sin(theta) = 42 / 100 theta = sin^(-1)(0.42) theta ≈ 24.8 degrees west of south Show more…
