Will Give Brainliest and 25 Points
1. In what way does the horn's pitch change for the observer as the car gets closer, and why does that change happen?
2. When a horn is moving away from an observer the sound waves from it will pass by the observer (more or less), frequently, causing the pitch to (get lower or higher).

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.)
