Final answer:
The work done in lifting a 10kg box 15m off the floor is calculated using the weight of the box and the distance it is lifted. With the weight being 98 N and the distance 15 m, the work done is 1470 J, which closely matches option B, 1,500 Joules.
Step-by-step explanation:
The work done in lifting an object is calculated using the formula Work (W) = Force (F) × Distance (d), where Force is the weight of the object, and Distance is how high the object is lifted.
The work done in lifting a 10kg box 15m off the floor is calculated using the weight of the box and the distance it is lifted. With the weight being 98 N and the distance 15 m, the work done is 1470 J, which closely matches option B, 1,500 Joules.
The weight of the object is calculated as its mass multiplied by acceleration due to gravity (g = 9.8 m/s²). In this case, a 10kg box is lifted 15m off the floor. Therefore, the work W can be calculated as:
- Weight (F) = 10 kg × 9.8 m/s² = 98 N
- Work (W) = 98 N × 15 m = 1470 J
Since 1470 J is not one of the provided options, the closest answer, based on typical rounding rules, would be B. 1,500 Joules.
