Determining maximum vertical height A block slides down a curved frictionless track and then up an inclined plane. The mass of the block is the point mass m. The coefficient of friction between the block and the incline is μk = 0.30 Use energy methods to find the maximum vertical height up the plane that the block reaches for θ = 45°, and h = 0.65 m. Mgymax = mgh-Wfk Mgymax = mgh- μkCos θ ∆x ymax = h- μkCos θ ∆x This is about how far I have come. Not sure if it is right though. I am not sure if ∆x should actually be ∆y or if either should be in the problem. I am seeking a direction on what to do next to complete this problem. I appreciate any help.
