2. A2 .00 kg ball is dropped from the top of a 10.0 m high building. a. Calculate the potential energy AND kinetic energies at: 10 m

**a. Calculation of Potential and Kinetic Energies at 10m:*** **Potential Energy (PE):** PE = mgh, where m is the mass (2.00 kg), g is the acceleration due to gravity (9.8 m/s²), and h is the height (10.0 m). PE = (2.00 kg) * (9.8 m/s²) * (10.0 m) = 196 Joules* **Kinetic Energy (KE):** At the initial height (10.0 m), the ball is just beginning its descent. It has not yet started moving, so its velocity is 0 m/s. Therefore, its kinetic energy is also 0. KE = (1/2)mv² = (1/2) * (2.00 kg) * (0 m/s)² = 0 JoulesSo, at 10.0 m:* **Potential Energy (PE) = 196 Joules*** **Kinetic Energy (KE) = 0 Joules**
