Problem
Blocks X (upper) and Y (lower) are in contact, X resting on Y. A horizontal force is applied to Y so that both blocks accelerate together without slipping.
(a) State the direction of the frictional force acting on block X at the interface.
(b) State the direction of the frictional force acting on block Y at the same interface.
(c) Give a brief reason for each direction stated above.
