A car is about to pass through an arc bridge, as shown in the figure below. Given that the speed of the car is 5 m/s constantly, determine the magnitude and direction of the car’s acceleration at thehighest point, B, and at the end of the bridge, point C (assume the car is still on the bridge). For a parabola that has a general equation of (y = ax2 + bx + c) , the x coordinate of the vertex can be found by    (-(b/2a))

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.
