On sept 8 2004 the genesis spacecraft crashed because the parachutedid not open. The 210kg capsule hit the ground at 311km/h and penitrated the ground to a depth of 81cm.
what was the acceleration (assume to be constant) inm/s2 during the crash.what force did the ground exert on the capsulehow long did this force last.
