1. The problem statement, all variables and given/known data A block of mass 4.0 kg is put on top of a block of mass M = 6.0 kg. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 19 N must be applied to the top block. The assembly of blocks is now placed on a horizontal, frictionless table. (a) Find the magnitude of the maximum horizontal force F that can be applied to the lower block so that the blocks will move together. 1 N (b) Find the magnitude of the resulting acceleration of the blocks. 2 m/s2 3. The attempt at a solution I'm really not sure how I would go about solving this. What I did was this: 19N - mu*4*9.8 = 0 To try and find the coefficient of friction between the two blocks but I'm not sure if that's right and even if it is, how I would go about finding the rest of the solution to the problem. Please help!
