Three forces with magnitudes of 10. newtons, 8 newtons, and 6 newtons acting concurrently on an object produce equilibrium. The resultant of the 6-newton and 8-newton forces has a magnitude of (1) 0.0 N (2) between 0.0 N and 10. N (3) 10. N (4) more than 10. N. What is the total number of components into which a single force can be resolved? (1) an unlimited number (2) two components (3) three components (4) four components at right angles to each other. A lawnmower is pushed with a constant force F, as shown in the following diagram. As angle θ between the lawnmower handle and the horizontal increases, what happens to the horizontal and vertical components of F? (1) The horizontal component decreases and the vertical component decreases. (2) The horizontal component decreases and the vertical component increases. (3) The horizontal component increases and the vertical component decreases. (4) The horizontal component increases and the vertical component increases. The following diagram shows a person exerting a 300.-newton force on the handle of a shovel that makes an angle of 60.° with the horizontal ground. Calculate the magnitude of the component of the force perpendicular to the ground. A vector makes an angle θ with the horizontal. The horizontal and vertical components of the vector will be equal in magnitude if angle θ is (1) 30.° (2) 45° (3) 60.° (4) 90.°. Which terms represent a vector quantity and the scalar quantity of the vector's magnitude, respectively? (1) acceleration and velocity (2) mass and force (3) speed and time (4) displacement and distance. The fundamental units for a force of one newton are (1) meters / second² (2) kilograms (3) meters / second² / kilogram (4) kilogram • meters / second².
