A lift that weighs 300N moves a man with a weight of 950N upwards by 12m. How much work is done to move the lift this height?

## Step 1: The first step in solving this problem is to understand the concept of work done in physics. The work done on an object is equivalent to the force applied to it multiplied by the displacement it moves while the force is applied. This can be represented mathematically as , where is the work done, is the force applied, is the displacement, and is the angle between the force and the displacement. ## Step 2: In this problem, the force is the total weight of the lift and the man, which is . The displacement is the distance the lift moves upwards, which is . The angle is because the force and the displacement are in the same direction (upwards). ## Step 3: Substitute the values of , , and into the formula for work done. ### ## Step 4: Calculate the work done. ###
