Take four objects to feel . a. write down in order how hot/cold they are. Estimate the temperature of each object . write it below the object . remember to include units
b. did you write the order of object (from coldest to warmest ) correctly ?
c. did you estimate the temperatures correctly ? If not , explain the difference between your thinking and actual values ?

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 = ?
