A particle starts from the origin at t = 0 with an initial velocity having an x component of 28.7 m/s and a y component of -16.4 m/s. The particle moves in the xy plane with an x component of acceleration only, given by 3.17 m/s². Determine the x component of velocity after 5.91 s. Answer in units of m/s.
A) 50.86
B) 47.34
C) 53.25
D) 45.92
