A block of mass M = 495.0 g sits on a horizontal tabletop. The coefficients of static and kinetic friction are 0.589 and 0.381, respectively, at the contact surface between table and block. The block is pushed on with a 13.7 N external force at an angle O with the horizontal. a) What angle with respect to the horizontal will lead to the maximum acceleration of the block for a given pushing force? Submit Answer Incorrect. Tries 1/99 Previous Tries b) What is the maximum acceleration? Submit Answer Tries 0/99
