Aparticle which is moving due east at 4ms 3ms. find the change in velocity. changes direction and starts to move due south at 1. rain falls vertically in still air with a constant velocity of 15ms. if a gale suddenly springs up and the wind blows horizontally at 20ms, calculate the resultant velocity of the rain (magnitude and direction) 2. find the magnitude and direction of a 7n and 24n force perpendicular to each other 3.

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 = ?
