1. The problem statement, all variables and given/known data A 55kg block is released on a ramp which is frictionless. The ramp is 20 meters long and at the bottom it is moving 8m/s. What is the angle of the ramp? 2. Relevant equations I am looking for the angle but cannot for the life of me figure it out. 3. The attempt at a solution I have set out my variables as m=55kg, d=20m and v=8m/s I drew out a triangle and have no idea how to do it.
