Homework Statement



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

Homework Equations



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

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.
