2 A block is placed against the vertical front of a cart as shown in figure below. (a) (3 marks) Draw the free-body diagram of the block when it does not fall. (b) (5 marks) What acceleration must the cart have so that block A does not fall? The coefficient of static friction between the block and the cart is us. (c) (2 marks) How would an observer on the cart describe the behavior of the block?
