WebFeb 9, 2016 · Use std::sqrt to compute the square root. Given mass and energy as numeric types, you can use use std::sqrt (2.0 * energy / mass) to compute the speed. I take care to write 2.0 to force the floating point overload of std::sqrt to be used, and to ensure that the division is not an integral one.
