Un grupo de seis personas compiten estirando la cuerda en grupos de 3. Los primeros 3 tienen fuerzas equivalentes de 25N. Del otro lado de la cuerda, 2 de los competidores aplican fuerzas de 15 N cada uno y el último del grupo solamente estira con 5 N de fuerza. Calcular la resultante gráfica y analíticamente. ¿qué grupo gana?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
