Apositron is an antimatter version of the electron, having exactly the same mass. when a positron and an electron meet. they annihilate, converting all of their mass into energy. (a) fund the energy released, assuming negligible kinetic energybefore the annihilation. (b) if this energy is given to a proton in the form of kinetic energy, what is its velocity"? (c) if thisenergy is given to another electron in the form of kinetic energy. what is its velocity?

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
