The car is traveling at a speed of 95 km/h as it approaches point A. Beginning at A, the car decelerates at a constant rate of 2 m/s2 until it gets to point B, after which its constant rate of decrease of speed is 0.9 m/s2 as it rounds the interchange ramp. Determine the magnitude of the total car acceleration: a) just before it gets to B, b) just after it passes B, and c) at point C.

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.
