- A particle has a mass of 1.6E-27kg and a momentum of 2.2E-18 kg.m/s. What is the speed of the particle? Express your answer in units of c, the speed of light. Keep four significant digits.Many expressions in special relativity contain the gamma (y) factor. 1 Y √1-v²/c² In the equation, u is the speed of some object or reference frame and c is the speed of light. Find the numerical value of y for each of the listed speeds. U = 0, 1 Y = V = 0.450c, Y = V = 0.980c, Y = 5.03The dimensionless parameter γ is used frequently in relativity. As γ becomes larger and larger than 1, it means relativistic effects are becoming more and more important. A. What is γ if v = 0.28c? B. What is γ if v = 0.53c?
