A particle is projected horizontally with a speed v from a height H. It lands a horizontal distance R from the place of the launch as shown in the diagram. A second particle is projected horizontally from the same height with a speed of 2v. Neglecting air resistance the horizontal distance travelled by the particle is

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.
