A force vector F, points due east and has a magnitude of 170 newtons. A second force F2 is added to F₁. The resultant of the two vectors has a magnitude of 310 newtons and points along the (a) east/ (b) west line. Find the magnitude and direction of F₂. Note that there are two answers. (a) (b) Number i 310 Number i newtons newtons

In the figure, the net external force on the 51.8 kg mower is horizontal to the right. If the force of friction opposing the motion is 22.4 N, and the pushing force from the guy is 470.1N and the direction is 46.9 degrees downward along the handle of the mower. What is the magnitude of the net force on the mower?

Two individuals are attempting to relocate a sofa by applying forces in the indicated directions. If F₁ = 490 N and F2 = 400 N, determine the vector expression for the resultant R of the two forces. Then determine the magnitude R of the resultant and the angle which it makes with the positive x-axis (measured counterclockwise from the x-axis). I F2 69⁰ -1 F₁ Answers: R= j) N R = e= i B i+ i N

Two forces act on a single point. The first force is 200N in the direction of S30◦W and the secondforce is 150N due east. Write each of these forces in vector form and then find the magnitude of theresultant vector.

Find the resultant of these three forces. Note the angle give for F3 is the angle between F2 and F3; to find the angle to use to get F3's x and y components, add the given angles together. F₂ = 3150 N F3 = 3680 N 42.0⁰ 120.0° F₁ = 2550 N

Two forces, F₁ and F2, act at a point. The magnitude of F₁ is 8.50 N, and its direction is an angle 65.0° above the negative direction of x-axis in the second quadrant. The magnitude of F2 is 5.00 N, and its direction is an angle 52.1° below the negative direction of x-axis in the third quadrant. What is the x-component of the resultant force? What is the y-component of the resultant force? What is the magnitude of the resultant force?

A barge is pulled by the two tugboats shown in the following figure. One tugboat pulls on the barge with a force of magnitude 4,800 units of force at 15° to the right of the line AB (see the figure) and the other tugboat pulls on the barge with a force of magnitud 5,500 units of force at 12° to the left of the line AB. (Assume the +x-direction is to the right and the +y-direction is up along the page.) !A 5,500 units 4,800 units 15° 12 Barge (View from above) iB

Jason is pulling a box across the room. He is pulling with a force of 19 newtons and his arm is making a 46 angle with the horizontal, what is the horizontal component of the force he is pulling with?
