    Force
In summary, the conversation discussed the use of energy concepts and force to calculate the distance a block will travel when it is compressed by a spring on a frictional surface. It was noted that while energy concepts can be used, the calculation may be more complex than using force and integrating an equation of motion. The equations for two distinct phases were also mentioned.

Moved from a technical forum, so homework template missing.
A block with initial speed 3 meter per second compress the spring in a frictional surface. Given that the spring constant k = 11000 N/M, mass of the block= 2.5 kg, coefficient of kinetic friction= 0.4. Calculate distance d that block travel until it momentarily stopped.

This is my method

initial KE = final PE + Work done by friction

However, is it possible to use force to calculate distance d since the acceleration of block depend on the extent of how much the block compress the spring.

Yes it is. Fill in the proper energy expressions (you do not yet have the right ones in your equation)

[edit] 'perhaps' :rolleyes: you will need two equations for two distinct phases in this exercise

Oh, and: dear lover, :welcome:

Yes, but it won't be nearly as simple as just using energy concepts. Essentially you'll have to integrate an equation of motion where the acceleration is changing with position.

Ah... I missed the actual question. So my reply may look somewhat weird :smile:
Thanks, Gneill, for answering that part.
 

Related to Is it possible to calculate this question with force

1. Can force be calculated using a formula?

Yes, force can be calculated using the formula F = m x a, where F is force, m is mass, and a is acceleration. This is known as Newton's second law of motion.

2. How do you measure force?

Force can be measured using a device called a force meter or spring scale. These tools measure the amount of force applied to an object in units of newtons (N).

3. Is it possible to calculate the force of an object at rest?

No, the force of an object at rest cannot be calculated. The formula F = m x a only applies to objects in motion. If an object is at rest, the force acting on it is equal to 0.

4. Can force be calculated in different directions?

Yes, force can be calculated in different directions. This is known as vector addition, where the forces acting on an object in different directions are added together to determine the overall force.

5. Are there any real-life applications of calculating force?

Yes, calculating force is important in many real-life applications, such as engineering, physics, and sports. It helps us understand the motion of objects and how forces affect them.
