I just need help with J. it is not 76.4 degrees 

At the instant the displacement of a 2.00 kg object relative to the origin is
(2.00 m)
+ (4.00 m) - (3.00 m) K, its velocity is
(2.61 m/s)
+ (1.57 m/s)
+ (6.37 m/s)
and it is subject to a force
(1.47 N)
(8.39 N) + (8.16 N) K. Find the acceleration of the object ((a), (b) and (c) for
and
components respectively), the angular
%3D
momentum of the object about the origin ((d), (e) and (f) for , J and K components respectively), the torque about the origin acting on the object ((g), (h) and (i) for ,
and
components respectively), and (j) the angle between the velocity of the object and the force acting on the object.
