A skateboarder of mass M initially moves with velocity V on a horizontal path. The skateboarder travels a distance D as she slows to a stop. Assume friction is constant. What variable(s) would you need to calculate Kinetic Energy?
Mass
Velocity
Height
Potential Energy
A new skateboarder of mass M initially moves with velocity 4V on a horizontal path. The skateboarder travels a new distance as she slows to a stop. Assume friction is constant. How does this new distance compare to a skateboarder with velocity V?

A new skateboarder of mass M initially moves with velocity V on a horizontal path. The skateboarder travels a new distance as she slows to a stop because friction is now doubled. How does this new distance compare to when we have friction F?

A new skateboarder of mass 2M initially moves with velocity 4V on a horizontal path. The skateboarder travels a new distance as she slows to a stop because friction is halved. How does this new distance compare to the original skateboarder (Mass M, velocity V, friction F)?
