Physics

Given:

Mass of the object:

Initial speed of the object:

Frictional force:

 

We need to calculate the distance the object will travel before coming to a stop. Since the object comes to rest, its final speed is .

 

Use the work-energy theorem

The work done by the frictional force is equal to the change in kinetic energy of the object.

 

1. Initial kinetic energy:

 

2. Final kinetic energy: Since the object comes to rest, its final kinetic energy is:
