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.)

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
