A 3 kg object is sliding down an incline of 40° with respect to the horizontal. The coefficient of kinetic friction between the incline and object is 0.4. The initial velocity of the object is 2.0 m/s.
a.) Draw a free body diagram for the situation labeling all forces present.
b.) Write the Newton’s Second Law equation for the forces acting on the object perpendicular to the incline.
c.) Write the Newton’s Second Law equations for the forces acting on the object parallel to the incline.
d.) Calculate the normal force acting on the object.
e.) Calculate the acceleration of the object.
Given:
The mass of the object is .
The inclination .
The coefficient of kinetic friction is .
The initial velocity of the object is .
Introduction:
The kinetic friction is a force of friction when solid bodies are able to slip over each other. This force is directly proportional to coefficient of kinetic friction and normal reaction.
