a stack of 3 books slides acorss the floor while slowing down. the coefficient of friction between the bottom book and the floor is 0.2. if each book is 0.2kg, what is the acceleration of the books? what is the force of friction acting the top book that keeps the stack together?

When you push a 1.80-kg book on a tabletop, it takes 2.25 N to start the book sliding. Once it is sliding, however, it takes 1.50N to keep the book moving with constant speed. What are the coefficients of static and kinetic friction between the book and the table top?

Alitz 1) - K 7 Mi →1 ext 7 Lo esc Bi A block of volume 600 × 10-6 m³ is held by a string at rest in honey as shown. Pblock = 5023 kg/m³, Phoney 1400 kg/m³, and g = 10.0 m/s2. What is the magnitude of the tension force on the block, in Newtons? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed.
