34. Imagine that a wood block is sliding along the surface of a desk. Can the frictional forces involved in this interaction change the momentum of the two-body system thought of as the Earth (including the desk) and the block? Yes, because it will provide a negative impulse to the block. Yes, because it will cause a negative impulse to the Earth. No, because the net force on the block will be zero. No, because there is no net external force on the system.
