Alaser pointer is placed on a platform that rotates at a rate of 60 revolutions per minute. the beam hits a wall 10 m away, producing a dot of light that moves horizontally along the wall. let θθ be the angle between the beam and the line through the searchlight perpendicular to the wall.

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 = ?
