A spring has a spring constant of 40 N/m40\text{ N/m}40 N/m. Calculate the work done in stretching this spring by 0.25 m0.25\text{ m}0.25 m from its unstretched position.
Two perpendicular forces, 5.0 N5.0\text{ N}5.0 N acting horizontally and 12.0 N12.0\text{ N}12.0 N acting vertically, pull an object.
Calculate the magnitude of the resultant force on the object.
Two perpendicular forces, 5.0 N5.0\text{ N}5.0 N acting horizontally and 12.0 N12.0\text{ N}12.0 N acting vertically, pull an object.
A student draws a scale diagram of these forces where 1 N1\text{ N}1 N is represented by 1.5 cm1.5\text{ cm}1.5 cm. Determine the length of the vector that represents this resultant force in the diagram.
