Notice that the stopwatch is set to zero. Advance the video to this point and reset the stopwatch. Then advance the video until the roller coaster train has moved the distance equal to the length of the train car. What time does the stopwatch show now

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° 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.)

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
