A cleaner is pushing an 11 kg dustbin across a level floor at constant speed. The coefficient of friction between the dustbin and the floor is 0.10. (a)If the cleaner is pushing horizontally, what is the magnitude of the force he exerts on the dustbin? (b)If he pushes at an angle of 30° down from the horizontal, what must the magnitude of his pushing force be to keep the can moving at constant speed?

A bedroom bureau with a mass of 42 kg, including drawers and clothing, rests on the floor. (a) If the coefficient of static friction between the bureau and the floor is 0.59, what is the magnitude of the minimum horizontal force that a person must apply to start the bureau moving? (b) If the drawers and clothing, with 17 kg mass, are removed before the bureau is pushed, what is the new minimum magnitude?

A worker pulls a 15-kg crate in a straight line on a level surface by imparting a horizontal tension of 80 N to the free end of a cable whose other end is attached to the crate. If the coefficient of static friction is 0.40, what is the acceleration of the crate?
