Fish are hung on a spring scale to determine their mass (most fishermen feel no obligation to report the mass truthfully).
(a) What is the force constant of the spring in such a scale if it stretches 7.90 cm for a 10.5 kg load?
(b) What is the mass of a fish that stretches the spring 5.50 cm?
(c) How far apart are the half-kilogram marks on the scale?
