- 10. Net Force Calculation (Multiple Forces): An object experiences three forces: 10 N to the right, 5 N to the left and 8 N upward.Calculate the net force in both the horizontal and vertical directions 11. Force and Friction A person applies a force of 100 N to push a box across a floor. If the frictional force is 70 N what is the net force acting on the box? 12. Free-Body Diagram Interpretation: A free-body diagram shows an object with a 50 N force upward, a 50 N force downward, and a 20 N force to the right. What can you conclude about the motion of the object? 13. Acceleration of a Falling Object: A 5 kg object is falling freely under gravity. Assuming no air resistance, what is the net force acting on the object? (Use a=9.8m/s^2 14. Newton's First Law Application: A hockey puck slides on ice at a constant speed until it hits a rough patch and slows down. Explain this situation using Newton's First Law. 15. Force Required to Lift an Object: What force is required to lift a 10 kg object at a constant speed? Explain your reasoning. (Hint, Look at question 3 for a)
