Some runners train with parachutes that trail behind them to provide a largedrag force. These parachutes are designed to have a large drag coefficient. Onemodel expands to a square 1.8mon a side, with a drag coefficient of 1.4. Arunner completes a 200mrun at 5.0m/swith his chute trailing behind. Howmuch thermal energy is added to the air by the drag force

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.)
