Um carrinho de mão, que se movimenta sobre uma ponte, como mostra a figura, onde o corpo se desloca do ponto A, considerada posição inicial (S0) e o ponto B, considerado a posição final (SF) a uma aceleração constante de 15 m/s e um intervalo de tempo de 21 segundos, avaliando que a variação de espaço percorrido é calculada pela diferença entre a posição final e a inicial.

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 = ?
