The graph shows how the relativistic momentum of an object varies with speed. The -axis shows the speed as and the -axis shows the momentum, , divided by the speed of light, . Use the formula to find the rest mass of the object.
An object is traveling at 75% of the speed of light in a frame . The object has a rest mass of 2 kg. How much greater is the relativistic momentum of the object than the classical momentum of the object? Give your answer to 3 significant figures.
At what speed is the relativistic momentum of an object equal to twice its classical momentum? Give your answer to 3 significant figures.
