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)?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
