A space vehicle is coasting at a constant velocity of 20.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.390 m/s2 in the +x direction. After 49.0 s, the pilot shuts off the RCS thruster. After the RCS thruster is turned off, find the following quantities.
