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.

8. The car is traveling at 30 mi/h when the traffic light 295 ft ahead turns yellow. The driver takes 1 s to react before he applies the accelerator. If the car has a constant acceleration of 5 ft/s² and the light remains yellow for 5 s, will the car reach the light before it turns red? How fast is the car moving when it reaches the light? Ans. No. 66.7 ft/s

box answer
A race car enters the circular portion of a track that has a radius of 65 m. When the car enters the curve at point P, it is traveling with a speed of 120 km/h that is increasing at 5 m/s2. Three seconds later, determine the x and y components of velocity and acceleration of the car. The x component of the total acceleration is m/s2.? The y component of the total acceleration is – m/s2.? The x component of the linear velocity is – m/s.? The y component of the linear velocity is – m/s.? Note: please show step by step solution.
