Solving a Physics Problem: Find Velocity of Block at Bottom of Loop

[Cglez1280]

Homework Statement

This is for my ap physics summer work and is giving me some trouble and could use any help

A small block, with a mass of 250 g, starts from restart the top of the apparatus shown above. It then slides without friction down the incline, around the loop then onto the final section on the right. The maximum height of the incline is 80 cm, and the radius of the loop is 15 cm.

Find the velocity of the block at the bottom of the loop.
Mass=.25Kg Gravity=9.8 height=0.8m diameter of loop=.3m

Homework Equations

GPE=mgh KE=.5mv^2

Hi Cglez1280, Welcome to PF!

What "trouble" did you run into ? Can you explain?
Did you obtain a result for the velocity?

Note that the forum rules state that you need to show an attempt at solution.
