During a flight in which a helicopter starts from rest at t = 0, the cartesian components of its acceleration are ax = 0.6t m/s2 and ay = 1.8 – 0.36t m/s2. (a) what are the normal and tangential components of the helicopter’s acceleration when it is 10 m horizontally from its starting point? (b) what is the radius of curvature at this instant?
