You're on a roll — here's the explanation for ITEM 1. ITEM 1 In a certain village, a very old woman died after a small paw-paw had hit her head as she was seated under the paw-paw tree. Many people were surprised because the paw-paw was very small and the tree was very tall. When they asked the chairperson how this was possible he told them that it was due to energy. This confused the villagers more and they came to you for assistance. The chairperson was correct; the death was due to energy. Step 1: Understand potential energy. An object at a certain height possesses gravitational potential energy (PE). This energy is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height from which it falls. Since the tree was "very tall," the paw-paw had a large initial height (h). Step 2: Understand the conversion of energy during the fall. As the paw-paw falls from the tall tree, its gravitational potential energy is converted into kinetic energy (KE), which is the energy of motion. The formula for kinetic energy is KE = (1)/(2)mv^2, where v is the velocity of the object. Due to the large height, the paw-paw gains a very high velocity just before impact. Step 3: Explain the impact. Even though the paw-paw had a "very small" mass, its high velocity due to the tall tree meant it possessed a significant amount of kinetic energy upon impact. This large amount of kinetic energy, transferred rapidly to the woman's head, caused severe trauma, leading to her death. The key is that the height of the fall significantly increases the velocity of the object, leading to a high kinetic energy at impact, regardless of the object's small mass. What's next? Send 'em!
