Suppose the initial position of an object is zero, the starting velocity is 3m/s and the final velocity was 10m/s. The object moves with constant acceleration. Which part of a velocity vs. time graph can be used to calculate the displacement of the object? A. The area of the rectangle under the line
B. The area of the rectangle above the line
C. The area of the rectangle plus the area of a triangle under the line
D. The area of a rectangle plus the area of the triangle above the line

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 = ?
