Cannot determine the work done with the given information.

Solución

To determine the work done by a force, we can use the formula: \[ W = F \cdot d \cdot \cos(\theta) \] where: - \( W \) is the work done, - \( F \) is the magnitude of the force, - \( d \) is the distance over which the force is applied, - \( \theta \) is the angle between the force and the direction of motion. However, the problem does not provide the distance \( d \) or the angle \( \theta \). To proceed, we need to make some assumptions or require additional information. If we assume that the force is applied in the direction of motion (i.e., \( \theta = 0^\circ \)), then \( \cos(0) = 1 \), and the formula simplifies to: \[ W = F \cdot d \] If we assume a specific distance, we can calculate the work done. Let's analyze the options provided: 1) 405 J 2) 500 J 3) 900 J 4) 4500 J 5) 5600 J To find the distance \( d \) for each option, we can rearrange the formula: \[ d = \frac{W}{F} \] Given \( F = 100 \, \mathrm{N} \), we can calculate \( d \) for each option: 1) For \( W = 405 \, \mathrm{J} \): \[ d = \frac{405}{100} = 4.05 \, \mathrm{m} \] 2) For \( W = 500 \, \mathrm{J} \): \[ d = \frac{500}{100} = 5.0 \, \mathrm{m} \] 3) For \( W = 900 \, \mathrm{J} \): \[ d = \frac{900}{100} = 9.0 \, \mathrm{m} \] 4) For \( W = 4500 \, \mathrm{J} \): \[ d = \frac{4500}{100} = 45.0 \, \mathrm{m} \] 5) For \( W = 5600 \, \mathrm{J} \): \[ d = \frac{5600}{100} = 56.0 \, \mathrm{m} \] Without additional context about the distance or the angle, we cannot definitively determine which option is correct. If you have more information about the distance or the angle at which the force is applied, please provide it so we can calculate the work done accurately.

Bonus Knowledge

To determine the work done by the \( 100-\mathrm{N} \) force, you can use the formula for work, which is: \[ W = F \cdot d \cdot \cos(\theta) \] where \( W \) is work, \( F \) is the force, \( d \) is the distance moved in the direction of the force, and \( \theta \) is the angle between the force and the direction of motion. Assuming the force is applied in the direction of motion (i.e., \( \theta = 0°\), and thus \( \cos(0°) = 1\)), we need to know the distance. Without knowing the distance, we can only speculate on the answer. Depending on how the distance is set, we can derive possible values. For example, if the distance \( d \) was \( 4.5\, \mathrm{m} \), the work done would be \( W = 100\, N \times 4.5\, m = 450\, J \). Given the options provided, if you can determine the distance moved, that will help finalize the exact answer from the ones listed!
