3. A truck (375 slugs) was travelling east with an unknown velocity when it entered into a head-on collision with a car. The car (200 slugs) was initially travelling west with a speed of 44 ft/sec. The vehicles stuck together in the collision, travelled east for a displacement of 120 feet in 4s before coming to rest. Calculate the truck's before collision velocity. [115 ft/sec] Before Collision 375 slug U₁=? 44 ft/sec Truck 200 slug Car At Collision Displacement, s = u+v 2 t After 120ft and 4s

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.
