Q14. As shown in the image below, the 20-kg box is pulled up the inclined plane with a constant velocity of 4.7 m/s. If the coefficient of kinetic friction between the box and the inclined plane is µ = 0.1, determine the power of force F. 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 m/s². F Your Answer: Answer 30° units
