- The Point Of This Question Is To Compare Rest Energy And Kinetic Energy At High Speeds An Alpha Particle A Hellum Nucl 1 (45.92 KiB) Viewed 92 times
The point of this question is to compare rest energy and kinetic energy at high speeds. An alpha particle (a hellum nucleus) is moving at a speed of 0.9987 times the speed of light. Its mass is (6.40×10−27 kg). (a) What is its rest energy? ] (b) Is it okay to calculate its kinetic energy using the formula 21mv2 ? Yes, because v≪<c. No, because this formula isn't valid for speeds near the speed of light. Yes, because the formula 21mv2 for kinetic energy is always correct. (c) What is its kinetic energy? (d) Which is true? The kinetic energy is much smaller than the rest energy. The kinetic energy is approximately equal to the rest energy. The kinetic energy is much bigger than the rest energy.
