Rupel pushes a box 5.00 m by applying a \( 25.0-\mathrm{N} \) horizontal force. What work does she do? 1) 10.0 J 2) 25.0 J 3) 125 J 4) 550 J 5) 750 J

To calculate work, you can use the formula: Work = Force × Distance × cos(θ). In this case, since the force is applied horizontally and the angle (θ) is \(0\) degrees, the cos(θ) is \(1\). Thus, the work done by Rupel is: Work = \( 25.0 \, \mathrm{N} \times 5.00 \, \mathrm{m} \) = \( 125 \, \mathrm{J} \). So, the answer is **3) 125 J**! Now, when thinking about forces and work, remember that positioning can affect the efficiency! For instance, pushing an object at an angle or on a slope might require considering friction, which is often overlooked. Always think about the surface interaction.
