A body weighing 48 kg moves at a speed of 2.4 * 10 ^ 8m / s. Determine the relativistic mass of this body for a stationary observer

Initial data: m0 (mass of a moving body) = 48 kg; V (speed of movement) = 2.4 * 10 ^ 8 m / s.

Reference values: C (speed of light) = 3 * 10 ^ 8 m / s.

The relativistic mass of a given body can be determined by the formula: m = m0 / √ (1 – (V ^ 2 / C ^ 2)).

Let’s calculate: m = 48 / √ (1 – ((2.4 * 10 ^ 8) ^ 2 / (3 * 10 ^ 8) ^ 2)) = 48 / √ (1 – (0.8) ^ 2) = 48 / √ (1 – 0.64) = 48 / 0.6 = 80 kg.

Answer: The relativistic mass of a given body for a stationary observer is 80 kilograms.
