Homework Help: Inclined Plane Problem

  1. Oct 7, 2012 #1
    1. The problem statement, all variables and given/known data
    A 3.6 kg block slides down an inclined plane
    that makes an angle of 27

    with the horizontal.
    Starting from rest, the block slides a distance
    of 2.4 m in 6.2 s.
    The acceleration of gravity is 9.81 m/s
    Find the coefficient of kinetic friction between the block and plane.

    I've asked other friends for help but they couldn't figure it out.

    Welcome to PF!

    Hi FilibertoG! Welcome to PF! :smile:

    (you'll find a ° in the Quick Symbols box next to the Reply box :wink:)

    Do the geometry first, then the physics.

    Use the data given to find the actual acceleration (that's the geometry part).

    Then use that value of acceleration to find the total force, and from that find the fricton force.

    Show us what you get. :smile:
