Final answer:
The work done lifting the box is calculated using the formula Work = Force x Distance. Given the weight of 100 N and a vertical lift of 1.5 m, the work done is 150 Joules (Option A).
Step-by-step explanation:
The amount of work done while lifting a box is calculated using the formula Work = Force x Distance. Since the weight of the box is given as 100 N, and it is lifted vertically 1.5 m, the work done lifting the box can be calculated as follows:
Work = Weight x Height
Work = 100 N x 1.5 m
Work = 150 J
Therefore, the correct answer to how much work is being done lifting the box is 150 Joules (Option A).
After the box is lifted, if it is held there, no additional work is done because work is defined as the transfer of energy when a force is applied over a distance, and while holding the box still, there is no distance over which the force is applied.
