# Schwarzschild

The Schwarzschild radius is the radius at which the escape velocity of a spherically symmetric, non-rotating body is the speed of light. The Schwarzschild radius of the human body can be expressed to three significant figures as \( \overline{abc} \times 10^{-27} \text{m}\). Determine the value of \( \overline{abc} \) given that the human body is made into the shape of a sphere and that the average mass of the human body is \( 70\text{kg} \).
