An underwater research drone (ROV) is traveling in a straight horizontal line to the right at a constant depth. The horizontal forces acting on the drone are shown in the diagram below:

An underwater drone traveling to the right. A horizontal arrow pointing to the right represents the forward thrust, labeled 'Propulsion thrust = 580 N'. Two horizontal arrows pointing to the left represent the resistive forces: one labeled 'Water drag = 340 N' and the other labeled 'Cable tension = 290 N'.

a.

Determine the magnitude of the resultant horizontal force on the drone.

b.

Describe the motion of the drone while these forces are acting.
