2) The ballistic pendulum is a simple device to measure projectile speed v by observing the maximum angle to which the box of sand with the embedded projectile swings. Calculate the pre-impact speed of the 40- gram projectile if the 16-kg box of sand swings up to a maximum angle of 0 = 23° after impact. #1 2 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.
