On September 8, 2004, the genesis spacecraft crashed in Utah desert because it's parachute did not open. The 210-kg capsule hit the ground at 311 km/h and penetrated the soil to a depth of 81.0 cm.
1) Assuming it to be constant, what is its acceleration (in m/s^2) during the crash?
2) Assuming it to be constant, what is its acceleration (in g's) during the crash?
3) What force did the ground exert on the capsule during the crash? Express the force in newtons.
4) What force did the ground exert on the capsule during the crash? Express the force as a multiple of the capsule weight.
5) For how long did this force last?
