A model depicts two balloons of the same size with identical negative charges being moved toward one another at the same speed. How will the balloons interact with each other? A.) They will repel, moving in opposite directions at the same speed.

B.) They will repel, moving in the same direction at different speeds.

C.) They will attract, moving in the same direction at the same speed.

D.) They will attract, moving in opposite directions at different speeds.

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 = ?
