Force A has an magnitude of 99.1 N and makes an angle of 45.9 degrees with respect to positive x-axis, in the first quadrant. Force B has an magnitude of 59.9 N and makes an angle of 27.2 with respect to negative y-axis, in the third quadrant. What is the magnitude of the net force (in N) of A and B on object C?arrow_forwardIs the following statement true or false? Explain. The resultant of the weight and the force required to move an object up an inclined plane is a vector perpendicular to the plane. Choose the correct answer below. O A. The statement is false because the resultant will always be a vector that is pointing up from the object on the inclined plane, at a 90° angle to the plane itself. O B. The statement is false because the resultant will always be a vector that is pointing in the opposite direction that the object is moving along the inclined plane, at a 90° angle to the vector representing the force of gravity. OC. The statement is true because the resultant will always be a vector that is pointing down from the object on the inclined plane, at a 90° angle to the plane itself. O D. The statement is true because the resultant will always be a vector that is pointing in the same direction that the object is moving along the inclined plane, at a 90° angle to the vector representing the force…arrow_forward
- Two forces act on an object. The first force has a magnitude of 19.0 N and is oriented 58.0° counterclockwise from the +x-axis, whereas the second force has x- and y-components (-25.0 N, 14.5 N). Express the magnitude and direction of the net force. magnitude: N direction: counterclockwise from the +x-axisarrow_forward2. In mechanics, force is a vector quantity and has a unit of Newtons (N). The force F₁ with a magnitude of 54.0 N is applied at an object at the origin in the direction of 25° above the negative x-axis. A second force F₂ with a magnitude of 41.0 N is applied at the same object in the direction of 68° above the positive x-axis. Determine the magnitude and direction of the resultant of the two forces.arrow_forwardWhat is the x and y component of the resultant force?arrow_forward

The tire remains stationary in spite of the three pulls. Alex pulls with force of magnitude 202 N, and Charles pulls with force of magnitude 148 N. Note that the direction of Charles' force is not given.

In the figure below, a force F, of magnitude 6.70 units acts on a crate at the origin in a direction 0 = 26.0° above the positive x-axis. A second force F, of magnitude 5.00 units acts on the crate in the direction of the positive y-axis.
