You're working on something mental when learning sign language. It would not be emotional, because that would be something like learning to cope. It wouldn't be community because you aren't working on it with the community and it wouldn't be physical because it doesnt involve pushing your body.
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.
