The arctic tern flies from the arctic to the antarctic and back every year, a total distance of 22,000 miles! in late summer, the terns start their migration south, and it takes about 3 months to go the 11,000 miles. what is the average velocity, in miles per day, that these birds travel? (remember, velocity also includes direction! )

Apossible explanation for a set of facts that can be tested by further investigation is called

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
