Text Solution

AI Generated Solution

To determine the directional and magnitude of the frictional force acting on a stationary rock being pushed to the right with a force of 100N, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Applied Force**: The rock is being pushed to the right with a force of 100N. 2. **Determine the State of Motion**: The rock is stationary, meaning it is not moving despite the applied force. ...
