In fig. A is a 1kg block and B is a `0.5kg` block. (a) Find the minimum weight of block C which must be placed on A to keep it from sliding , if `mu_(s)` between A and the table is `0.2`. The block C is suddenly lifted off A. What is the acceleration of block A if `mu_(k)` between A and the table is `0.2` ?

To solve the problem, we will break it down into two parts: 1. Finding the minimum weight of block C that must be placed on block A to prevent it from sliding. 2. Calculating the acceleration of block A after block C is suddenly lifted off. ### Part 1: Finding the Minimum Weight of Block C **Step 1: Identify the forces acting on block A.** ...
