Concept explainers

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

A 5.0 kg mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown. The scale reads in newtons.
a. What does the spring scale read just before the mass touches the lower spring?
b. The scale reads 20 N when the lower spring has been compressed by 2.0 cm. What is the value of the spring constant for the lower spring?
c. At what compression distance will the scale read zero?
