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.
