Final answer:
The kinetic energy of a proton traveling at a speed of 2550 m/s is approximately 5.443 × 10-21 Joules or 3.396 MeV.
Step-by-step explanation:
The kinetic energy of a proton with a given mass and velocity can be calculated using the classical physics formula KE = ½mv2. In this case, the mass of a proton (m) is 1.67 × 10-27 kg and the velocity (v) is 2550 m/s. Plugging these values into the formula gives us:
KE = ½ × 1.67 × 10-27 kg × (2550 m/s)2
After calculating, the kinetic energy comes out to be approximately 5.443 × 10-21 Joules or 3.396 MeV (using 1 eV = 1.602 × 10-19 Joules).
