The resistance R to penetration x of a 0.30-kg projectile fired with a velocity of 535 m/s into a certain block of fibrous material is shown in the graph. Represent this resistance by the dashed line and compute the velocity v of the projectile for the instant when x = 63 mm if the projectile is brought to rest after a total penetration of 80 mm. Answer: v= i Rmax R, N m/s x, mm 80

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.
