Aforce does work on a 50 g particle as the particle moves along the following straight paths in the xy-plane: 25 j from (0 m, 0 m) to (5 m, 0 m); 35 j from (0 m, 0 m) to (0 m, 5 m); -5 j from (5 m, 0 m) to (5 m, 5 m); -15 j from (0 m, 5 m) to (5 m, 5 m); and 20 j from (0 m, 0 m) to (5 m, 5 m).

is this a conservative force?

if the zero of potential energy is at the origin, what is the potential energy at (5m, 5m)?

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.)
