As shown in the following drawing, the half-angle of the shock wave cone generated with a supersonic transport is 45°. What is the speed of the plane relative to the speed of sound? Hint: Utilize 340m/s as the speed of sound an electron has a speed of 0.72 c.
a) Discover the speed of a proton that has the same kinetic energy as the electron.
b) Find the speed of a proton that has the similar momentum as the electron.
