A book of mass 6.7 kg is resting on a flat level table. You push down on the book at an angle of 23.5 degrees fromthe horizontal with force of magnitude 433 N. The book starts to slip and is sliding across the table. What is themagnitude of the force of kinetic friction from the table on the book? The coefficient of kinetic friction between thetable and the book is μk = 0.40.
Block B has mass 5.00 kg and sits at rest on a horizontal,frictionless surface. Block A has mass 2.00 kg and sits at rest on topof block B.
