A 45 g bullet is fired with a velocity of 400 m/s at an angle ø = 5 ° into a square panel whose sides measure b = 200 mm and has a mass of 9 kg. Knowing that h = 150 mm and that the panel is initially at rest, determine a) The distance h required if the horizontal component of the impulse reaction at A is to be zero. b) The corresponding velocity of the center of the panel immediately after the bullet is embedded. Please include the free body diagram if necessary

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.
