1. Parcels are moved via conveyor with velocity vo down to a colinear incline that is static at point A where sliding begins. The parcels eventually fall off at point B, which is 7.0 m past A. If the coefficient of kinetic friction on the incline is 0.40, find the velocity of the conveyor belt, vo, such that the parcels have zero velocity at point B. 7m 15°

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.
