Q15. As shown in the image below, the 17-kg crate is being hoisted by the motor. If at this instant shown the velocity of point P on the cable is vp = 2.6 m/s and the speed is increasing at 1.3 m/s², what is the power input supplied to the motor if its efficiency is e = 0.63? Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper Sl unit. Take g = 9.81 m/s².

Question
**Question 15:** As shown in the image below, the 17-kg crate is being hoisted by the motor. If at this instant shown the velocity of point \( P \) on the cable is \( v_P = 2.6 \, \text{m/s} \) and the speed is increasing at \( 1.3 \, \text{m/s}^2 \), what is the power input supplied to the motor if its efficiency is \( e = 0.63 \)? Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit. Take \( g = 9.81 \, \text{m/s}^2 \). **Diagram Explanation:** The diagram illustrates a system where a crate labeled "A" is being hoisted vertically by a motor. The motor is connected to a pulley system. The point \( P \) on the cable is marked, and the downward velocity \( v_P \) of this point is shown. The motor and pulleys are depicted with typical mechanical components, and the crate is suspended by the cable. **Your Answer:** | Answer | units | |--------|-------| | | |
