Answer:
Larry did 600 joules of work by pushing the chair.
Explanation:
Certainly! Let’s break down how to calculate the work done by Larry when pushing the chair. Work is defined as the product of the force applied and the displacement in the direction of the force. Here are the steps:
Identify the Given Information:
Work Done (W): 600 Joules
Force Applied (F): We need to find this.
Displacement (d): The distance the chair moves due to Larry’s force.
Use the Work Formula: The work done by Larry can be calculated using the formula: [ W = F \cdot d \cdot \cos(\theta) ]
(W) represents the work done (600 J in this case).
(F) is the force applied by Larry.
(d) is the displacement (distance the chair moves).
(\theta) is the angle between the force and the direction of displacement. Since Larry pushes the chair horizontally, (\theta) is 0°, and (\cos(0) = 1).
Solve for Force (F): Rearrange the formula to solve for (F): [ F = \frac{W}{d \cdot \cos(\theta)} ] Substituting the given values: [ F = \frac{600 , \text{J}}{d} ]
Find the Displacement (d): Unfortunately, we don’t have the exact displacement value. If you have additional information about how far the chair moved, we can proceed further. Otherwise, we’ll need that missing piece of data.
Remember that work is done when a force acts over a distance. Larry’s effort of 600 Joules indicates that he did work, but without knowing the displacement, we can’t determine the exact force he applied. If you have more details, feel free to share them, and we can continue solving the problem!
