A snow mobile has a position vector 42.1 m at 98.0 degrees counter clockwise from the x axis and velocity of 5.35 m/s at 38.0 degrees. it is moving with a constant acceleration of 1.33 m/s^2 at 210 degrees. After 7.00 s have elapsed determine its velocity vector and its position vector. Any help understanding how to solve this sort of problem would be appreciated.
