Question

Fish are hung on a spring scale to determine their mass (most fishermen feel no obligation to truthfully report the mass). (a) What is the force constant of the spring in such a scale if it the spring stretches 8.00 cm for a 10.0 kg load

Answer 1

K= 1226.25 N/m

Step-by-step explanation:

Given: mass m = 10 kg, Distance x= 8 cm = 0.08 m, g= 9.81 m/s²

By Hook's Law

F=K x

F=W=mg = 10 kg x 9.8 m/s² = 98.1 N

to Find Spring constant k = F/x = 98 N /0.08 m

K= 1226.25 N/m
