A 600 kg elevator initially moving upward undergoes motion represented by the velocity vs time graph shown. Calculate the force of tension supporting the
elevator. (Enter your answer as four significant figures without units or spaces.
Ex) If the force=1598.3 N enter "1598") *

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.)
