    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    ugh wait no sorry gsinθ-a/gcosθ=uk?
  4. U

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    gsinθ-a/-gcosθ=uk?
  5. U

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    gsinθ + μkgcosθ = a?

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    wait no negative
  8. U

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    -cosθ x m x a / sinθ = Uk?
  9. U

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    -(m x 9.81 cosθ)?
  10. U

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    -(m x 9.81 sinθ) + ((m x 9.81 sinθ) x Uk)=-(m X a) sooooo Uk=-ma?

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    Fk=Uk x (m x 9.81 sinθ) and -weight + friction= - resultant im not sure what combines those?
  12. U

    How Do You Calculate the Coefficient of Kinetic Friction on a Ramp?

    so weight and friction so -weight + friction= -resultant
