A cube of steel has a volume of 1.00 cm^3 and a mass of 8.00 g when at rest on Earth. If this cube is now given a speed u = 0.900c, what is its density as measured by a stationary observer? Note that relativistic density is defined as E/(c^2 * V).

Step 1
First, we need to find the rest energy (E0) of the cube. We can use the formula E0 = mc^2, where m is the mass and c is the speed of light. Show moreā¦

A cube of steel has a volume of $1.00 \mathrm{~cm}^{3}$ and a mass of $8.00 \mathrm{~g}$ when at rest on the Earth. If this cube is now given a speed $u=0.900 c$, what is its density as measured by a stationary observer? Note that relativistic density is $E_{R} / c^{2} V$.
