A force of $400\,\text{N}$ pulls a crate with weight $500\,\text{N}$ up a ramp at constant speed, as illustrated. Some of the work done raises the crate’s gravitational potential energy $E$, while the remainder is work done $W$ against friction. What are the values of $E$ and $W$?
- A$E = 1500\,\text{J},\; W = 500\,\text{J}$
- B$E = 1500\,\text{J},\; W = 2000\,\text{J}$
- C$E = 2000\,\text{J},\; W = 2500\,\text{J}$
- D$E = 3500\,\text{J},\; W = 500\,\text{J}$
