Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

According to the article Alien Antimatter Crashes into Earth 2 :
More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an
collided with an
antineutrino
the antimatter answer to the nearly massless neutrino
electron, it could produce a cascade of other particles. The "Glashow resonance -
phenomenon is hard to detect, in large part because the antineutrino needs about 1,000

times more energy than what's produced in the most powerful colliders on Earth.
Let's
compare
this event to an ordinary baseball with a mass of 146 g. Please use three
significant figures in your calculations.

Now consider a baseball with the same kinetic energy as that of the
Glashow resonance. What speed in m/s would correspond to this energy?

dx 4x 3. In so-called "natural units" (which is just a sneaky way to let us ignore a bunch of constants), the relativistic kinetic energy of a rigid body is given by the formula 1 КЕ — т V1 – v2 where m is the rest mass of the body and v is its relative speed. Alien scientists on a space station are observing an object falling into a black hole. As the object falls, it is disintegrating, losing mass at a rate of 3 (so its mass is changing at a rate of -3). How fast is the kinetic energy of the main part of the object changing when its mass is 20, its velocity is .7, and it is accelerating at a rate of .1 (remember that acceleration is the derivative of velocity with respect to time: a = dt 1Note that this formula does not make sense when v > 1. That is because in natural units, a speed of 1 corresponds to the speed of light, and nothing with positive rest mass can go that fast.
