# A crate is pulled \(2.5 \, \text{m}\) at constant velocity along a \(25^\circ\) incline. The coefficient of kinetic friction between the crate and the plane is \(0.250\). What is the efficiency of this procedure?

A crate is pulled \(2.5 \, \text{m}\) at constant velocity along a \(25^\circ\) incline. The coefficient of kinetic friction between the crate and the plane is \(0.250\). What is the efficiency of this procedure?

- **A.** \(35\%\)
- **B.** \(45\%\)
- **C.** \(55\%\)
- **D.** \(65\%\)
- **E.** \(75\%\)
