A small inspection drone is modelled as a particle of mass 2 kg moving in a horizontal plane. Two horizontal forces, (6i+8j)(6\mathbf{i} + 8\mathbf{j})(6i+8j) N and (−2i+4j)(-2\mathbf{i} + 4\mathbf{j})(−2i+4j) N, act on the drone.
Find the resultant force acting on the drone.
Find the magnitude of its acceleration.
