第一題
Let S,S',S" be coordinate systems with coincided x-axes, parallel y-axes, and
parallel z-axes. At time 0 with respect to all three clocks, S,S',S" coincide.
Suppose that system S"(respectively, S" and S") moves at a postive velocity v_1
(respectively, v_2 and v_3) measured by S(respectively, S' and S). Thus, the
correspondence of coordinates from S(respectively,S' and S) to S'(respectively,
S" and S") is described by T_(v_1) (respectively,T_(v_2) and T_(v_3). If
T_(v_3) = T_(v_2)T_(v1), then
v_1 + v_2
v_3 =
