Friction and Gravity

Consider a 2.0-kg Physics textbook pressed against a wall as shown (position is in meters and time is in seconds) in the animation. Given that m_s= 0.5 and that m_k =0.4 between the wall and the textbook, determine the force that must act on the book perpendicular to the wall. Start
