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?
