That was just a standard missile, not the Kinzhal, which goes deep underground.
The Russians have replaced the Iskander missile with the Kinzhal (Dagger.) Read what Wikipedia has to say of the Kinzhal. Please note that vectors ( forces in a direction) are additive so when the Mach 10 Kinzhal is launched at Mach 2 from a Mig 31, the resulting speed is Mach 12.
Because it flies at hypersonic speeds within the atmosphere, the air pressure in front of it forms a plasma cloud as it moves, absorbing radio waves (Plasma stealth).
The high speed of the Kinzhal gives it better target-penetration characteristics than lighter, slower cruise-missiles. With advanced maneuvering capabilities, high precision and hypersonic speed, some sources give it the name “carrier killer” due to its alleged ability to disable and possibly even sink a 100,000 ton supercarrier with a single strike. With a mass of 2,000 kg (4,400 lb) and a speed of Mach 12 (including a 500 kg warhead and the other parts of the missile), the Kinzhal has more than 16.9 gigajoules of kinetic energy, or the equivalent of 4,000 kg (8,818 pounds) of TNT.
