El sistema de la figura está formado por una línea semi-infinita, una línea de longitud finita de longitud “a” (ambas uniformes, colineales, horizontales y de densidad λ); un disco uniforme horizontal de densidad σ y una pequeña carga Q (todos situados a una distancia a del punto P). Cuánta carga, qo, debe tener una pequeña esfera de masa = 0,25 g colocada en el punto P, para se acelere con una magnitud de 6,25x108 m/s2. Considere a=2 cm, Q = 8ηC, λ = 0,5μC/m y σ = 8,5 μC/m2.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
