### Physics Problem: Calculating Forces and Acceleration **Problem Statement:** A teacher moves a 16.9 kg desk across the room by applying a 188 N horizontal force. The coefficient of friction (μ) is 0.39. **Tasks:** 1. **Find \( F_g \) (Gravitational Force):** \( F_g = \_\_\_ \) N 2. **Find \( F_N \) (Normal Force):** \( F_N = \_\_\_ \) N 3. **Find \( F_f \) (Frictional Force):** \( F_f = \_\_\_ \) N 4. **Find the acceleration of the desk:** \( \_\_\_ \) m/s² **Diagram:** - A horizontal desk (mass = m) with an applied force (F) moving to the right. - The force is depicted by an arrow showing the direction of movement. **Instructions:** Complete the calculations for each box and submit your answers. (Note: Include relevant formulas for gravitational force, normal force, and frictional force. Use Newton’s second law to find acceleration based on the forces.) **Additional Information:** The diagram illustrates the concept of forces acting on an object on a flat surface, highlighting the applied force, the mass of the object, and the direction of motion.
