An object with mass 70 kg moved in outer space. when it was at location < 11, -33, -4> its speed was 3.0 m/s. a single constant force < 200, 420, -140> n acted on the object while the object moved from location < 11, -33, -4> m to location < 14, -29, -7> m. then a different single constant force < 140, 210, 160> n acted on the object while the object moved from location < 14, -29, -7> m to location < 18, -34, -4> m. what is the speed of the object at this final location?
