finding maximum velocity??
A block of mass M = 275.0 g sits on a horizontal tabletop. The coefficients of static and kinetic friction are 0.54 and 0.38, respectively, at the contact surface between table and block. The block is pushed on with a 12.0 N external force at an angle θ below the horizontal.
(a) What angle will lead to the maximum acceleration of the block for a given pushing force?
20.8° above the horizontal
(b) What is the maximum acceleration?
43 m/s^2
those were the answer given. I know how you get the degrees but i am having trouble how to find the maximum acceleration... can you guy help me?
