Research recently reported the first optical atomic trap. In this device, beams of laser light replace the physical walls of conventional containers. The laser beams are tightly focused. They briefly (for 0.5s) exert enough pressure to confine 500sodium atoms in a vloume of 1.0x10^-15m^3. The temperature of this gas is 0.00024K, the lowest temperature ever reached for a gas. Compute the root-mean-square speed of the atoms in this confinement
