As the marble rolls down the hill its potential energy is converted to kinetic energy its height decreases but its velocity increases.
A marble rolls down a track and around a loop the loop.
The loop has a radius of r.
Im having trouble with this physics question and need some help how do i answers this question.

To make that loop the centripetal force should be equal to the weight of the marble thus the centripetal acceleration and the velocity at the top of the loop is given by mg m ac m v 2 r v.
The marble has mass m and radius r.
That is the minimum value of h if the marble is to reach the highest point of the loop without leaving the track.
I know i need to use conservation of momentum or energy.

The marble rolls down the track and around a loop the loop of radius r.
A marble of mass m and radius r rolls along the looped rough track.
First of all i would like to say that the answer floris gave is the correct way to do the problem you ve set forward but i thought it worthwhile to note that the result 5 over 2 r r is the answer if rather than rolling a marble down the track you are sliding a cube.
