A girl rolls a ball up an incline and allows it to return to her. For the angle and ball involved, the acceleration of the ball along the incline is constant at 0.35g, directed down the incline where g is the gravitational acceleration. If the ball is released with a speed of 3.81 m/s, determine the distance, s (m) it moves up the incline before reversing its direction. Round off only on final answer expressed in three decimal places. ...

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.
