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.

1. A wood block of mass mw = 200 g is projected from the ground at a speed vo= 35 m/s and at an angle 0o = 50°. When at height h = 24 m the wood block was hit by a bullet of mass mb = 25 g which was moving at vb= 220 m/s and at an angle Ob = 70°. After the collision, the bullet embedded itself in the block and move together and land at point A on the ground.
