Transformers are used both to increase the voltage of electricity, so that it can travel long distances, and to decrease the voltage, so that the electricity can be used in your house with relative safety. If the voltage across two wires is raised to 2.5 x 105 V, what is its current if 1.0 x 105 W of power is provided?

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.)
