At the instant the displacement of a 2.00 kg object relative to the origin is d = (2.00 m)i + (4.00 m)j - (3.00 m)k, its velocity is v = (6.99 m/s)i + (3.66 m/s)j + (8.14 m/s)k and it is subject to a force f = (9.02 n)i - (3.34 n)j + (9.52 n)k. find the acceleration of the object ((a), (b) and (c) for i, j and k components respectively), the angular momentum of the object about the origin ((d), (e) and (f) for i, j and k components respectively), the torque about the origin acting on the object ((g), (h) and (i) for i, j and k components respectively), and (j) the angle between the velocity of the object and the force acting on the object.
