Answer:
3000 m/s
Explanation:
The kinetic energy is:
KE = 3/2 kT
where k is Boltzmann constant and T is absolute temperature.
Kinetic energy is also:
KE = 1/2 mv²
where m is the mass and v is the speed.
1/2 mv² = 3/2 kT
mv² = 3kT
v = √(3kT / m)
v = √(3 × 1.38×10⁻²³ J/K × (273 + 27) K / 1.38×10⁻²⁷ kg)
v = 3000 m/s
