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.

Question

2/236 A bicyclist rides along the hard-packed sand beach
with a speed UB = 16 mi/hr as indicated. The wind
speed is Uw = 20 mi/hr. (a) Determine the velocity
of the wind relative to the bicyclist. (b) At what
speed UB would the bicyclist feel the wind coming
directly from her left (perpendicular to her path)?
What would be this relative speed?
