How much rope would have to be pulled through to raise a 25 pound weight 15 feet

To determine how much rope needs to be pulled to raise a 25-pound weight 15 feet, we first need to consider the setup. If we're assuming a simple pulley system with no mechanical advantage (a single pulley where the rope is directly pulling the weight vertically), the length of the rope pulled will be the same as the height the weight is raised. Therefore, in this basic scenario:

- **Rope pulled = 15 feet**

So, you would need to pull 15 feet of rope to raise the weight 15 feet.

However, if the setup includes a pulley system with a mechanical advantage (such as a block and tackle), the amount of rope pulled would be greater depending on the number of pulleys used. For example:

- In a **2:1 pulley system** (one additional pulley), you would need to pull **30 feet of rope** to raise the weight 15 feet.
- In a **4:1 pulley system** (three additional pulleys), you would need to pull **60 feet of rope** to raise the weight 15 feet.
