The motorcycle is traveling at 50 m/sm/s when it is at A. The speed is then decreased at v˙=−(0.04s)m/s2, where s is in meters measured from A. Suppose that ρ = 150 m.   (b) Determine the magnitude of the acceleration of the motorcycle when it reaches B. Express your answer to three significant figures and include the appropriate units.   (c)  Determine the direction of the acceleration of the motorcycle when it reaches B measured counterclockwise from the negative x-axis. Express your answer using three significant figures.

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.
