Explanation:
The vertical velocity of the car at the given position and time is 4.905 m/s.
The given parameters:
- Initial angular velocity,
= 6.3 rad/s - Time of motion, t = 0.25 s
- Vertical displacement, y = 0.75 m
- Angular acceleration,
![\alpha = 0.95 \ rad/s^2](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%200.95%20%5C%20rad%2Fs%5E2)
<h3>What is vertical velocity?</h3>
- This is the linear velocity of an object in a vertical direction.
The angular velocity of an object in a circular motion is given as;
![\omega_f = \omega _0 + \alpha t\\\\\omega _f = 6.3 \ +\ 0.95 \times 0.25 \\\\\omega _f = 6.54 \ rad/s](https://tex.z-dn.net/?f=%5Comega_f%20%3D%20%5Comega%20_0%20%2B%20%5Calpha%20t%5C%5C%5C%5C%5Comega%20_f%20%3D%206.3%20%5C%20%2B%5C%20%200.95%20%5Ctimes%200.25%20%5C%5C%5C%5C%5Comega%20_f%20%3D%206.54%20%5C%20rad%2Fs)
The vertical velocity of the car at the given position and time is calculated as follows;
![v = \omega r\\\\v = \omega_f y\\\\v = (6.54 \ rad/s)\times (0.75\ m)\\\\v = 4.905 \ m/s](https://tex.z-dn.net/?f=v%20%3D%20%5Comega%20r%5C%5C%5C%5Cv%20%3D%20%5Comega_f%20y%5C%5C%5C%5Cv%20%3D%20%286.54%20%5C%20rad%2Fs%29%5Ctimes%20%280.75%5C%20m%29%5C%5C%5C%5Cv%20%3D%204.905%20%5C%20m%2Fs)
Thus, the vertical velocity of the car at the given position and time is 4.905 m/s.
