1. The barrel of the rifle shown is aimed at point A. The distance 8 is the space between points A and B, which the bullet strikes the wall at point B. If the muzzle velocity is 600 m/s. Determine the distance 8, if the constant gravitational acceleration is given as g=8.6 m/s² (4 points) If the bullet is forced to strikes the wall at point O by applied the wind, causing a constant acceleration of a=105.45 m/s². Determine the direction O of the wind, where the effect of gravitational acceleration of g=8.6 m/s² still exists. (6 points) a=105.45 m/s B 20° Horizontal 1000 m

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.
