Suppose a skateboarder is coasting initially at 7.5 m/s to the right across flat, rough ground (coefficient of friction = 0.125). How far will the skateboarder go before stopping. (Kinematics and forces will be used in combination)
The Attempt at a Solution
I'm not certain how to approach the question. The question doesn't state what the mass is, nor any applied force apart from the initial velocity. I know that the final velocity is 0.
