Question

More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an antineutrino — the antimatter answer to the nearly massless neutrino — collided with an 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.

 

1.What is the threshold antineutrino energy for the Glashow resonance in peta electronvolts (PeV)?

 

2.What is this threshold energy in units of joules?

 

3.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?

 

4.What is this rate in units of inches/second?
