Answer:

Sí se puede aplicar el Principio de Conservación de la Energía Mécanica siempre y cuando se considere los efectos de pérdida de energía a causa del rozamiento, de lo contrario, no se cumpliría el requisito de conservación derivado del citado principio de conservación.  

Explanation:

Consideremos que el cuerpo representa nuestro sistema de estudio, el cual se desplaza por una carretera y experimenta rozamiento, significando cambios en la energía cinética y potencial gravitacional. La presencia de rozamiento indica una disipación de la energía del cuerpo, cuya energía mecánica total disminuye, significando un sistema no conservativo.

Sí se puede aplicar el Principio de Conservación de la Energía Mécanica siempre y cuando se considere los efectos de pérdida de energía a causa del rozamiento, de lo contrario, no se cumpliría el requisito de conservación derivado del citado principio de conservación.

while racing on a flat track, a car rounds a curve of 28m radius and instantaneously experiences a centripetal acceleration of 1
liubo4ka [24]
When a body strictly moves on a curve, it's velocity at a point is tangential to the curve at that point.

Centripetal acceleration is the acceleration that a body experiences by the virtue of change in it's tangential velocity. It is directed towards the centre and mathematically is v^2/R where v is the speed at the instant.

So, 18 = v^2/R
v^2 = 504
v = 6√14
