Pushing on the pump of a soap dispenser

compresses a small spring. When the spring is

compressed 0.50 cm, its potential energy is

0.0040 J. What is the force constant of the spring?

Nola Robertson · Answer 1

EE = ½ kx²

0.0040 J = ½ k (0.0050 m) ²

k = 320 N/m

EE = ½ kx²

0.0094 J = ½ (320 N/m) x²

x = 0.0077 m

x = 0.77 cm
