A space vehicle is coasting at a constant velocity of 21.0 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 0.320 m/s in the +x direction. After 45.0 s, the pilot shuts off the RCS thruster. After the RCS thruster is turned off, find (a) the magnitude and (b) the direction of the vehicle's velocity relative to the space station. Express the direction as an angle measured from the +y direction.

II. Given the nth term formula, complete the first five terms of the sequence 1. an = 5n2 -2n for n ? 1 2. an = n/(n+1) for n?0 3. an = 4n2 â€“n - 1 for n ? 1 4. a_n= 2n^2+ n â€“ 3 for n ? 0 5. a1 = 3, a2 = 7, and an = 2an-1 + an-2 for n ? 3 III. Substitute the given values in the formula A = Pe^rt to find the missing quantity 1. P = 750,000, r = 18% per year, t = 8 years 2. A = 1,740,000, r = 7% per year, t = 5 years 3. A = 675,000, P = 425,000, r = 4% per year
