Friction, Speed, and Distance

  1. Jan 15, 2010 #1
    A 20kg object is initially moving at 2 m/s along a surface with a coefficient of friction of 0.02. Assuming that friction is the only force acting on the object, how far will the object travel? How long will the object be in motion? Do you need any additional information to answer these questions?

    This is a real-world situation, so I can provide additional information if necessary.

    You can use conservation of energy to find how far. Then you can easily use kinematics for the time.

    A real world problem would be a little more complex. If the surface on which the object is moving is horizontal you already have the information necessary to solve it.
