In a fixed-target experiment positrons are fired at a target of electrons at rest. What positron energy is required to produce a Z (mZ = 91.188 GeV)?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

The energy produced as a result of this flow of electrons from atom to atom is called
