Two elevators in adjacent shafts approach each other, one from the top and the other from the bottom. At a certain instant the elevators are 150m apart. The top elevator has a speed of 0.6m/s and accelerating 0.6m/s2, while the lower elevator has a speed of 0.9m/s and accelerating 0.3m/s2. Determine The height (meters) traveled by the upper elevator.0 answer should be 3 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.
