Question

Un vagón de 250 kg situado en la cima de una montaña rusa inicia su descenso por una rampa inclinado 60º sobre la horizontal. Si no tenemos en cuenta el rozamiento: a. Dibuja todas las fuerzas que actúan sobre el vagón. b. Calcula la fuerza y la aceleración con que desciende.

Answer 1

The forces acting on the wagon are gravity, tension, and normal force. The acceleration can be calculated using Newton's second law equation.

Step-by-step explanation:

a) The forces acting on the wagon are:

• Gravitational force (mg), pointing downward vertically
• Normal force (N), pointing perpendicular to the incline
• Force of tension (T), pointing along the incline

b) The gravitational force can be resolved into two components: one parallel to the incline and one perpendicular to it. The component parallel to the incline is responsible for the acceleration of the wagon. The component perpendicular to the incline cancels out the normal force.

The force of tension is equal to the gravitational force component parallel to the incline, and the acceleration can be calculated using Newton's second law equation: F = ma.

Um I don’t understand what your saying
