Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

**Problem 19-15:**

If the boxer hits the 75-kg punching bag with an impulse of \( I = 20 \, \text{N} \cdot \text{s} \), determine the angular velocity of the bag immediately after it has been hit. Also, find the location \( d \) of point \( B \), about which the bag appears to rotate. Treat the bag as a uniform cylinder.

**Diagram Explanation:**

- The diagram shows a boxer striking a hanging punching bag.
- The punching bag is depicted as a vertical yellow cylinder with a diameter of 0.5 meters.
- The bag hangs from a pivot point at \( A \), with a total height from the pivot to the bottom of the bag measuring 2.5 meters (1 meter from \( A \) to \( B \), plus 1.5 meters for the bag itself).
- The impulse exerted by the boxer on the bag is marked as \( I = 20 \, \text{N} \cdot \text{s} \).
- The point \( B \) is located 1 meter below the top pivot point \( A \), representing a point about which the bag seems to rotate after being hit.
- The goal is to calculate the angular velocity and the specific location \( d \) of point \( B \).
