A 1 kg block is at rest relative to a rough plane inclined at 30° to the horizontal. The entire inclined-plane assembly is then moved vertically upward with a constant velocity of 4 m·s⁻¹, while the block remains at rest relative to the plane. Taking g = 10 m·s⁻², what is the work done by the frictional force on the block during the next 2 s, as measured in the ground frame?
