### Power and Efficiency **Learning Goal:** As shown, a 55 kg crate is pulled up a θ = 65° incline by a pulley and motor system. Initially at rest, the crate is pulled \( s = 4.1 \, m \) up along the incline. Undergoing constant acceleration, the crate reaches a speed of \( 2.5 \, m/s \) at the instant it has traveled this distance. (Figure 1). **Figure 1 Explanation:** The diagram illustrates a crate being pulled up an inclined plane with an angle of inclination, \( \theta = 65° \). The pulley and motor system is depicted at the top of the incline. The position \( s = 4.1 \, m \) indicates the distance the crate has moved along the incline. The motion of the crate is assisted by a cable connected to the pulley. Additional Information: - Weather: Sunny - Temperature: 98°F
