During a test flight, a 9000-kg helicopter initially starts from rest. The acceleration of its center of mass from its initial position t=0 s to its final position at t = 10 s is given by a = 0.6ti + (1.8+ 0.36t)j (m/s2). Determine the magnitude of the resultant force acting on the helicopter at t = 6 s.
