Homework Help: Work and energy

  1. Aug 25, 2016 #1
    1. The problem statement, all variables and given/known data
    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
    2. Relevant 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.
