Text Solution

AI Generated Solution

To analyze the frictional force acting on the sofa being pushed across the floor, we can break down the situation step by step: ### Step-by-Step Solution: 1. **Identify the Applied Force**: The sofa is being pushed with a force of 75 N towards the right. 2. **Understand Friction's Role**: Friction always acts in the opposite direction to the motion of the object. Since the sofa is moving to the right, the frictional force will act to the left. ...
