Final velocity of the mass on an incline?

  1. Jul 4, 2009 #1
    A spring with a spring-constant 3.4 N/cm
    is compressed 27 cm and released. The 9 kg
    mass skids down the frictional incline of height
    13 cm and inclined at a 17◦ angle.
    The acceleration of gravity is 9.8 m/s2 .
    The path is frictionless except for a dis-
    tance of 0.5 m along the incline which has a
    coefficient of friction of 0.2.


    What is the final velocity vf of the mass?
