A bedroom bureau with a mass of 45.0 kg, including drawers and clothing, rests on the floor. (a) If the coefficient of static friction is 0.450, what is the magnitude of the minimum horizontal force that a person must apply to start the bureau moving to the right? (b) If the drawers and clothing, with 17.0 kg mass, are removed before the bureau is pushed to the right, what is the new minimum magnitude?
