For a production shoot, camera A travels next to car B at the same velocity v=30 mph on a straight road. Car B then enters a curve without change in speed while camera A continues along a staight path and stays due west of car B so that car B always appears to be traveling due east from camera A. (The value between r and -x is theta=50 degrees) -What is the difference in speed between camera A and car B? -What is the speed of car B relative to camera A

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.
