If an object is moving at #2 m/s# over a surface with a kinetic friction coefficient of #u_k=6 /g#, how far will the object continue to move?
Since the force and the distance travelled are in opposite directions, then
Also, since it force works uniformly over the entire movement until rest of object (i,e till
So, all in all, it reduces to
Now, force acting on the object is
So, that means
Solving this gives the given answer above.
