A plane heading S21°E with an an air speed of 375 mph encounters a wind blowing due east at 28 mph. a. Express the velocity of the plane vp relative to the air and the velocity of the wind vw in terms of i and j. Round components to 1 decimal place.   b. Find the velocity of the plane relative to the ground vg and the speed of the plane relative to the ground. Round the speed to the nearest mph.   c. Find the bearing of the plane relative to the ground. Round to the nearest tenth of a degree.

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.
