   The impact speed of Cosmos 482 is estimated at ~242 km/h.

   "With a mass of just under 500 kg and 1-m size, a TUDAT reentry analysis suggests an impact speed (after atmospheric deceleration) of about 65-70 meter per sec (~242 km/h), assuming the reentering lander did not break up or extensively ablate during reentry.

   The kinetic energy at impact is similar to that of a 40-55 cm large (after ablation) meteorite fragment."
