Find the magnitude and direction of the resultant R of the three vectors shown in Figure 1. The vectors have the following magnitudes: A = 5.0, B = 7.9, and C = 8.0. Express the direction of the vector sum by specifying the angle it makes with the positive x-axis, with the counterclockwise angles taken to be positive.​

Ways that industry and agriculture use physical properties to separate substances

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 = ?
