Object slides down frictionless ramp. Find acceleration.

  1. Oct 13, 2013 #1
    1. The problem statement, all variables and given/known data

    Hello, this is my first post here.
    I am trying to find acceleration for an object sliding down a ramp. I have the length + height of ramp.

    Height: 6.5cm
    Length: 130 cm

    2. Relevant equations

    I'm at loss here. Vectors are included and this is a kinematics question.

    3. The attempt at a solution

    Inverse Sin of 6.5/130 give me 2.9 degrees.
    Cos(2.9) x 130 is 129.8cm for the horizontal component.

    Thanks, for the answer, but my question doesn't have mass or friction involved. In elementary level physics.

    No friction, fine. But all objects have mass. Make use of the link for the no friction case. Maybe you won't need to know the mass.
