Compute all parts of given question:
Question: A block of mass M = 473.0 g sits on a horizontal tabletop. The coefficients of static and kinetic friction are 0.569 and 0.429, respectively, at the contact surface between table and block. The block is pushed on with a 13.1 N external force at an angle with the horizontal.
Part A: What angle with respect to the horizontal will lead to the maximum acceleration of the block for a given pushing force?
Part B: What is the maximum acceleration?
Please, show work so I can understand the concept. Thank you.
