- Understand the derivative of a function is the instantaneous rate of change of a function.
- Apply rates of change to displacement, velocity, and acceleration of an object moving along a straight line.

- A ball is thrown downward with a speed of 8ft/s from the top of a 64-foot-tall building. After t second, its height above the ground is given by .
(a). Find the velocity and acceleration functions.
(b). Determine how long it takes for the ball to hit the ground.
(c). Determine the velocity of the ball when it hits the ground.
- The rate of change of position is velocity, and the rate of change of velocity is acceleration. Speed is the absolute value, or magnitude, of velocity.
