can anybody helps me figure out this

describe

1.      The graph below is representative of the force applied to an object as it is pulled across a horizontal surface. Describe the motion of the object for the positions labeled in the graph.

2.      What relationship exists between the static/kinetic frictional force and the normal force on an object?

The graph below is representative of the force applied to an object as it is pulled across a horizontal surface. Describe the motion of the object for the positions labeled in the graph. What relationship exists between the static/kinetic frictional force and the normal force on an object?

Explanation / Answer

The graph indirectly represents friction force versus time as friction increases with external forces for static condditions

A.)body is at rest

B.)the body is at the verge of motion yet it not started its motion in that case we obtained maximum value of friction

C.)As inetic friction is less then static friction so point C represents that Body is is motion and force is decreasing with time

d.) Once the body starts its motion we just applied Kinetic friction which is less then static friction

2.) for static friction

F=mus*N where N is normal foorce and mus is coefficient of static friction

F-muk*N where N is normal foorce and muk is coefficient of kinetic friction
