Hello again!
Pendulums are common devices that scientists use to demonstrate concepts of motion, but they aren’t limited to the confines of a science classroom. In fact, pendulums are all around us. They are used to keep time (clocks) or to have fun on a playground (swings). Some pendulums, such as the one in the photograph, are used to demonstrate the Earth’s rotatation. In this lab activity, you will create a pendulum and manipulate its components to test factors that control the motion of its swing.

Explanation:
The average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.
The given parameters;
- s(t) = -9t² + 103t + 403
- time interval (4.499, 4.5), and (4.5, 4.501)
The average velocity of the bottle rocket over the intervals is calculated as follows;
when the interval = [<em>4.499, 4.5</em>]


when the interval = [<em>4.5, 4.501</em>]

The instantaneous velocity of the bottle rocket at time t=4.5;

Thus, the average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.
