In an asymmetric colliding beam experiment, a beam of electrons e" strike a beam of positrons e+ traveling in the opposite direction. suppose that the electrons are moving in the positive x-direction and the positrons are moving in the negative x-direction. denoting the position of an electron by xe, the position of a positron by xp, the position of the center of mass of an electron positron pair by x, and the mass of an electron or a positron by m, the position of the center of mass is given by the equation the speed of the positrons is 0.2c. calculate the velocity of the the collision between an electron and a positron produces (a) suppose the speed of the electrons is 0.95c and center of mass of an electron-positron pair. (b) suppose that a particle at rest in the center of mass system, which decays in 2.0 x 10-8 s. what will the lifetime of the be in the laboratory frame of reference? the asymmetric colliding beam technique has been used in an experiment performed by scientists at cornell university. the time-dilation effect makes the experiment possible. 0 90e toward the star sirius, which is 8.6 light years away

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
