2. El edificio Platinum, ubicado en Santiago, se mece con una frecuencia aproximada a 0,10 Hz. ¿Cuál es el periodo de la vibración?

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot
