Force on a helicopter using its position vector

(See attached file for full problem description with proper symbols)

The position of a 2.75 x 10^5 N training helicopter under test is given by
Vector r = (0.020 m/s3)t3î + (2.2m/s)tĵ - (0.060 m/s2)t2k

Find the net force on the helicopter at t =5.0 s.

Express the vector F in the form Fx, Fy , Fz , where the x, y, and z components are separated by commas.
