An object with mass $5.0\,\text{kg}$ is pushed up a slope at a constant speed of $2.0\,\text{m s}^{-1}$. Which calculation is used to find the change in gravitational potential energy between the bottom and the top?
- A$0.50 \times 5.0 \times 2.0$
- B$5.0 \times 9.8 \times 3.0$
- C$0.50 \times 5.0 \times 2.0^2$
- D$5.0 \times 9.8 \times 8.0$
