4. (25 points) Two boxes are at rest on a frictionless table. There is no friction between the two boxes. The box with mass My will be crushed if a force is applied to it that has a magnitude greater than the known value To. A force of magnitude P is to be applied to the first block, mass MA, at the fixed, known angle 0. a. (20 points) What is the largest value that P can have without the second box being crushed? MA MB b. (5 points) Find the maximum value that P can have without crushing the box if now the surface of the table is such that there is a coefficient of friction / between the table and first box, MA, but all other surfaces are still frictionless
