La distancia recorrida es la suma de las etapas de aceleración y velocidad constante (Travelled distance is the sum of the acceleration and constant speed stages). La aceleración es (The acceleration is):
La distancia recorrida es (The travelled distance is):
In order to solve this problem we must remember that kinetic energy is defined as the product of mass by velocity squared by a medium. Therefore using the following equation we have:
The friction force is the weight force times the coefficient of friction. So diving by the coefficient gives you the weight force which is equivalent to the normal force.
