Solve the all parts of given problem:
Problem: A 25 kg block is held against a compressed spring and then the spring is allowed to decompress giving the block a velocity. The block then slides to the right on a horizontal frictionless surface and then up a frictionless incline.
Part A: Choose the appropriate Conservation of Energy equation used to find the maximum height reached by the block on the incline.
Part B: Find the maximum height that the block reaches if the incline is 18.9? . All surfaces are frictionless, the spring constant is 1000N/m and the initial spring compression is 26.4cm.
Please explain how you came to your conclusion. Thank you.
