An object with mass 50 kg moved in outer space. When it was at location <10, -26, -6> its speed was 4.5 m/s. A single constant force <210, 300, -190> N acted on the object while the object moved from location <10, -26, -6> m to location <15, -17, -9> m. Then a different single constant force <90, 200, 170> N acted on the object while the object moved from location <15, -17, -9> m to location <20, -24, -4> m. What is the speed of the object at this final location

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
