dos masas de 8 kg estan unidas en el extremo de una varilla de aluminio de de 400 mm de longitud. la varilla esta sostenida en su parte mediaa, gira en circulos y solo puede soportar una tension maximade 800 N ¿cual es la frecuencia maxima de revolucion?

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?
