A bicycle moves along a straight road such that its speed is described by the continuous function f(t). You are asked to determine the magnitude of the displacement of the bicycle between 5.1 and 21 seconds. To do this, you must solve the integral below. What should the bounds on the integral be? Write your answer to one decimal place. As = fa f(t)dt a = Number b = Number seconds seconds

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.
