Roller Coaster Marbles How Much Height To Loop The Loop Science Projects Coaster Projects Roller Coaster
I know i need to use conservation of momentum or energy.
A marble rolls down a track and around a loop the loop. The marble rolls down the track and around a loop the loop of radius r. As the marble rolls down the hill its potential energy is converted to kinetic energy its height decreases but its velocity increases. 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. Figure cp12 85 shows a triangular block of swiss cheese sitting on a cheese board.
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. That is the minimum value of h if the marble is to reach the highest point of the loop without leaving the track. What minimum height must the track have for the marble to make it around the loop the loop without falling off.
Get more help from chegg. The marble has mass m and radius r. A marble of mass m and radius r rolls along the looped rough track. What minimum height h must the track have for the marble to make it around the loop the loop without falling off.
The loop has a radius of r. The marble rolls down a track and around a loop the loop of radius. 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.
When the marble goes back up the loop its height increases. The marble rolls down the track and around a loop the loop of radius r. The marble rolls down the track 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.
Im having trouble with this physics question and need some help how do i answers this question. The marble has mass m and radius r.
