Train A travels with a constant speed VA = 95 km/h along the straight and level track. The driver of car B, anticipating the railway grade crossing C, decreases the car speed of 70 km/h at the rate of 4.7 m/s². Determine the velocity VA/B and acceleration aA/B of the train relative to the car. Answers: VA/B = (i aA/B( i (C) B 61° i+ i i+ i 11° j) km/h j) m/s²

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.
