- On September 8, 2004, the Genesisspacecraft crashed in the Utah desert because its parachute did not open.The 210 kg capsule hit the ground at 311 km/h and penetrated the soilto a depth of 81.0 cm. How long did this force last?A net (unbalanced) external force of 100.0 N acts on an object of mass 20.0 kg whose initial speed is 10.0 m/s. The force acts in the opposite direction from the object's motion, and it acts for 1.00 s. What is the object's final speed, in m/s?A constant force of 200N is required to accelerate a 1600 kg trailer from rest to a speed of 25m/s. How much distance is covered by the trailer in that duration? I keep getting 2500m but it is within the given answers.
