Physics

Given data:

Mass of the block:

Initial speed of the block:

Frictional force:

 

We need to calculate the distance the block will travel before coming to a stop. The 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 block.

 

1. Initial kinetic energy:

 

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