A fisherwoman from Hamburg wants to weigh her fish. To this end, she plans a new fish store in which there is little space and builds the spring scale into the elevator. a) Draw a free body diagram for the forces acting on a fish that is being weighed on the spring scale. Choose a meaningful coordinate system, considering the sign of the force measured by the spring scale. b) Using a North Sea cod with a weight of W = 40 N, show how much more/less the fish would weigh if the elevator accelerated with a = 2 m/s² upward/downward. c) What does the scale show, if the elevator's cable breaks?
