Use the parallelogram rule to find the magnitude of the resultant force for the two forces shown in the figure. Round to
one decimal place.
-One rope pulls a barge directly east with a force of 61 newtons, and another rope pulls the barge directly north with a force of 58 newtons. Find the magnitude of the resultant force acting on the barge.
A) 119 newtons
B) 84 newtons
C) 3500 newtons
D) 3 newtons

Question

Quizplus · Accepted Answer

The magnitude of the resultant force can be found using the Pythagorean theorem since the forces are perpendicular to each other: $\sqrt{61^2 + 58^2} \approx 84.0$ newtons.
