The speedboat B is cruising to the north at 76 mi/hr when it encounters an eastward current of speed vC = 20 mi/hr but does not change its heading (relative to the water). Determine the subsequent velocity of the boat relative to the wind and express your result as a magnitude vrel and compass direction θ measured clockwise from north. The current affects the motion of the boat; the southwesterly wind of speed vW = 27 mi/hr does not.

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.
