WebAn alpha particle (a helium nucleus) is moving at a speed of 0.9992 times the speed of light. Its mass is (6.40 x 10-27 kg). (a) What is its rest energy? j (b) Is it okay to … Web25 mrt. 2024 · The formula for kinetic energy (KE) relates energy to mass (m) and velocity (v). KE = 1/2 mv 2 Because mass is always a positive value and the square of any value is a positive number, kinetic energy is always positive. Also, this means the maximum kinetic energy occurs when velocity is greatest, regardless of the direction of motion.
