1. A block with a mass of 10kg is initially at rest while held in contact with a compressed spring. The spring has a stiffness constant of 2000 N/m and is initially compressed by a length of 0.4 meters. Once the mass leaves the spring it will slide 1 meter across the surface of a table where 0.3 is the coefficient of kinetic friction. There are no frictional losses while the mass is in contact with the spring, and there are no losses due to air resistance. Only losses are due to the interaction with the table during the 1-meter slide. The surface of the table is 2 meters above the floor.

Transcribed Image Text:1. A block with a mass of 10kg is initially at rest while held in contact with a compressed spring.
The spring has a stiffness constant of 2000 N/m and is initially compressed by a length of 0.4
meters. Once the mass leaves the spring it will slide 1 meter across the surface of a table where
0.3 is the coefficient of kinetic friction. There are no frictional losses while the mass is in
contact with the spring, and there are no losses due to air resistance. Only losses are due to the
interaction with the table during the 1-meter slide. The surface of the table is 2 meters above the
floor.
What is the speed of the mass just before it hits the floor?

Expert Solution
Step 1
Given:
The mass of the block is .
The stiffness constant of the spring is .
The spring is compressed by 1 m.
The coefficient of the kinetic friction of the spring is 0.3.
The surface of the table is 2 m above the floor.
Introduction:
Frictional force refers to the force generated by two surfaces that contact and slide against each other. A few factors affecting the frictional force: These forces are mainly affected by the surface texture and amount of force impelling them together.
