Un electrón (masa = 9·10-31 kg) sale del cátodo de una lámpara de radio partiendo del reposo y viaja en línea recta hasta el ánodo, que está a 0,01 m de distancia, y llega con una velocidad de 6·106 m/s. Si la fuerza que lo acelera es constante (despreciar la fuerza gravitatoria sobre el electrón), calcular: La fuerza de aceleración. El tiempo que empleó en llegar al ánodo. La aceleración.

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
