A Marble Rolls Down A Track And Around A Loop The Loop

The loop has a radius of r.

A marble rolls down a track and around a loop the loop.

Get 1 1 help now from expert physics tutors. When the marble goes back up the loop its height increases. I know i need to use conservation of momentum or energy. A marble of mass m and radius r rolls along the looped rough track.

That is the minimum value of h if the marble is to reach the highest point of the loop without leaving the track. The marble rolls down the track shown in figure cp12 84 and around a loop the loop of radius r. 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 rolls down the track and around a loop the loop of radius r.

Figure 1 what minimum height h must the track have for the marble to make it around the loop the loop without falling off. The marble has mass m and radius r. The marble has mass m and radius r. What minimum height h must the track have for the marble to make it around the loop the loop without falling off.

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. The marble has mass m and radius r. Im having trouble with this physics question and need some help how do i answers this question. Get more help from chegg.
