The diagram illustrates a block resting on a slope. A constant force of $1.8\text{ N}$, acting parallel to the slope, is applied to the block. As a result, the block travels along the slope at constant speed. It covers a distance of $8.0\text{ m}$ up the slope and rises through a height $h$. The work done against the frictional force on the block is $4.8\text{ J}$. The weight of the block is $4.0\text{ N}$. What is the value of $h$?
- A$1.2\text{ m}$
- B$2.4\text{ m}$
- C$3.6\text{ m}$
- D$4.8\text{ m}$
