El bloque A de la figura se posiciona en una mesa horizontal sin fricción y es acelerado por una fuerza generada por el bloque B. B cae verticalmente mientras A se desliza horizontalmente sobre la mesa. Ambos bloques tienen una masa M. a).- La masa total del sistema es: b).- La fuerza que acelera A+B es el peso de c).- El peso de B es: d).- La aceleración del sistema es: Suponga que el bloque A tiene 1 kg de masa y B es un objeto de masa reducida (una pluma o moneda).e).- En comparación con el problema anterior, la aceleración del sistema es f).- En este caso, la aceleración de B es: Suponga que A es ahora una pluma o moneda, y B un objeto de masa 1 kg. Contesteg).- La aceleración del sistema es: h).- En este caso, la aceleración de B es: i).- En caÃda libre la aceleración es: j).- Si se lanza verticalmente hacia arriba un objeto, en su punto más alto la aceleración serÃa:

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
