An object with mass 100 kg moved in outer space. When it was at location <11, -21, -7> its speed was 4.0 m/s. A single constant force <250, 330, -140> N acted on the object while the object moved from location <11, -21, -7> m to location <16, -14, -10> m. Then a different single constant force <100, 260, 170> N acted on the object while the object moved from location <16, -14, -10> m to location <19, -21, -5> m. What is the speed of the object at this final location?
Find acceleration due to both the forces from Newton second law.
Also find distance between the given three points.
Then use equation of motion to find the final speed.
