1. A man pulls a suitcase of mass 15 kg with a force “F” inclined at an angle of 60° to the horizontal. The frictional force between the floor and the wheels of the suitcase is 10 N. What is the force required to produce an acceleration of 0.1 m/s2 on the suitcase?
2. Emily leaves her physics book of mass 1 kg on the top of the table that is inclined at an angle of 20°. What is the acceleration of the book if the coefficient of kinetic friction between the book and the inclined plane is 0.3?
