In anticipation of a long 6° upgrade, a bus driver accelerates at a constant rate of 1 m/s? while still on a level section of the highway. Knowing that the speed of the bus is 60 km/h as it begins to climb the grade and that the driver does not change the setting of his throttle or shift gears, determine the distance traveled by the bus up the grade when its speed has decreased to 35 km/h.

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.
