Example 11 Velocity and Acceleration
Recall that if the function
(b) Many experiments have shown that when an object is dropped, its acceleration (ignoring air resistance) is constant. This constant has been found to be approximately
The negative sign is used because the object is falling. Suppose an object is thrown down from the top of the
