The maximum kinetic energy KEmax of the ejected photoelectrons is plotted along the ordinate and the frequency f of the incident light is plotted along the abscissa. Determine the work function W0 (in joules) of the metal.

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.)
