A tugboat is towing a barge, as shown in the diagram.

A tugboat on the left is towing a barge on the right with a tow cable. The cable is angled upwards from the barge to the tugboat. The tension force in the cable exerts both a horizontal force forwards and a vertical force upwards on the barge.

The tension force in the tow cable causes:

  • a horizontal force forwards of 240 N240\text{ N}240 N
  • a vertical force upwards of 70 N70\text{ N}70 N

Calculate:

a.

The magnitude of the tension force in the tow cable.

[2]
b.

The angle (direction) of this tension force relative to the horizontal. Give your angle to two significant figures.
