a the wegiht of the object
b the velocity of the object
c the velocity of the object squared
d the square root of the velocity of the object
Homework Answers
Frictional force on an object does not depend on its velocity. Rather it is proportional to the normal force acting on the body from the surface. The normal force acting on a body kept on a horizontal surface is proportional to the weight of the object and therefore, the frictional force between a sliding object and the contact surface is proportional to the weight of the object.
Option (a) is the correct choice.
