Blocks A and C are connected by a string as shown. When released, block A accelerates to the right and block C accelerates downward. There is friction between blocks A and B, but not enough to prevent block B from slipping. If you stood next to the table during the time that block B is slipping on top of block A, you would see A. block B accelerating to the right. B. block B accelerating to the left. C. block B moving at constant speed to the right. D. block B moving at constant speed to the left.
