Deuterium (2h), when heated to sufficiently high tempera- ture, undergoes a nuclear fusion reaction that results in the production of helium. the reaction proceeds rapidly at a temperature, t, at which the average kinetic energy of the deuterium atoms is 8 × 10216 j. (at this temperature, deu- terium molecules dissociate completely into deuterium atoms.)
(a) calculate t in kelvins (atomic mass of 2h 5 2.015).
(b) for the fusion reaction to occur with ordinary h atoms, the average energy of the atoms must be about 32 × 10216 j. by what factor does the average speed of the 1h atoms differ from that of the 2h atoms of part (a)?

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 = ?
