Question

09 A particle moves in the xy plane, starting from the origin at t0 with an initial velocity v,20.0i-3.00j, where the unit of velocity is m/s. The particle experiences an acceleration in the x direction only that is given by a,4.00 m/s2. Find the magnitude of its average velocity from 1 = 0 to 5.00 s. A) 10.4 m/s B) 15.7 m/s C) 22.5 m/s D) 35.1 m/s E) 46.3 m/s

I know that the answer is a but what are the steps ??
