Final answer:
The work done while lifting the dog with a force of 300 N over a distance of 1.5 m is calculated using the formula W = F × d, resulting in 450 J. Hence, the correct answer is c) 450 J.
Step-by-step explanation:
To calculate the work done in lifting an object with a force over a certain distance, we can use the formula:
Work (W) = Force (F) × Distance (d)
In this case, the force is 300 N and the distance is 1.5 m, so the work done to lift the dog can be calculated as follows:
W = 300 N × 1.5 m = 450 J
Therefore, the correct answer is c) 450 J.
This type of problem is a typical physics calculation involving the concept of mechanical work, which is a measure of the energy transfer that occurs when an object is moved over a distance by an external force.
