PHYSICS-Net external Force

posted by on .

1. Two tugboats pull a barge across the harbor. one boat exerts of force of 7.5 x 10^4 N North, while the second boat exerts a force of 9.5 x 10^4 N at 15.0 degrees north of west. Precisely, in what direction does the barge move?


2. A traffic signal is supported by two cables, each of which makes an angle of 40.0 degrees with the vertical. If each cable can exert a maximum force of 7.50 x 10^2 N, what is the largest weight they can support?

    1. It moves in the direction of the resultant force

    2. Write an equation that says that the resultant vertical force is zero. With a bit of trigonometry, that will let you solve for the cable tension.
