Answer to Question #240450 in Physics for sunwoo

Question

A woman weighing 600 N steps on a bathroom scale that contains a stiff spring. In equilibrium, the spring is compressed 1.0 cm under her weight as shown in Figure 4. Find the force constant of the spring and the total work done on it during the compression.

Answer 1

$$k=\frac{F}{x}=\frac{600}{0.01}=60000\frac{N}{m}\\E=0.5(60000)(0.01)^2=3\ J$$
