Here is the problem which I am struggling on, please help me!

Problem: A block is placed on a frictionless ramp at a height of 11.5 m above the ground. Starting from rest the block slides down the ramp. At the bottom of the ramp, the block slides onto a frictionless horizontal track without slowing down. At the end of the horizontal track, the block slides smoothly onto a second frictionless ramp. How far along the second ramp does the block travel before coming to a momentary stop, as measured along the incline of the ramp?

Part A: After the block comes to a complete stop on the second ramp, it will then begin moving back down the second ramp. What is the speed of the block when it is 6.25 m, vertically, above the ground?

Please show me step by step or type in formulas used. I am so lost!!
