Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

A man pushes an object to the right and exerts a force which has a horizontal compotent of F = 33 N. A horizontal frictional force has a magnitude of f = 15 N which opposed the horizontal component of the fushing force. The mass of the object is m = 31 kg. Write an expression for the magnitude of the acceleration of the object. If the object starts at rest what is the speed in meters per second at t = 2.00s? If the man stops pushing the object at t = 2.00s and the firctional force is constant what is the distance in meters does to object slide before coming to a rest?
