这道题怎么解---Here is the extracted content from the image: **Question 8** **(Points: 6分)** **Question Stem:** 如图所示，水平地面上的物体重 G=100N，受与水平方向成37°角的拉力 F=60N，受摩擦力 f=16N，已知 sin37°=0.6, cos37°=0.8, 求: **Sub-questions:** (1) 物体所受的合力 (2) 物体与地面间的动摩擦因数 **Other Relevant Text (potentially options for a previous question):** A. 50N B. 20N C. [content cut off] **Mathematical Formulas/Given Values:** * Weight of object, G = 100N * Pulling force, F = 60N * Angle with horizontal = 37° * Friction force, f = 16N * sin37° = 0.6 * cos37° = 0.8 **Chart/Diagram Description:** * **Type:** The problem description states "如图所示" (As shown in the figure), indicating that a diagram is part of the problem. However, the actual diagram is not visible in the provided image. * **Handwritten Notes/Sketches:** To the right of the question, there are some unclear handwritten notes and partial sketches, likely related to solving the problem: * A vertical arrow pointing upwards, labeled "F₁". * A dashed horizontal line extending rightwards from the base of "F₁". * A diagonal arrow pointing downwards and rightwards, possibly representing a force component, with a partial label "F₂" or similar. * Some crossed-out text, partially legible as "hott - 16N =". * A partially visible number "12". These handwritten elements are incomplete and do not form a coherent, describable chart or diagram.
