Explanation:
The given data is as follows.
Electric field between plates without dielectric,
Electric field between the plates with dielectric, .
Permittivity of free space, =
Now, we will determine the charge density as follows.
=
=
Thus, we can conclude that the charge density on each surface of the dielectric is .
The car’s velocity at the end of this distance is <em>18.17 m/s.</em>
Given the following data:
- Initial velocity, U = 22 m/s
- Deceleration, d = 1.4
- Distance, S = 110 meters
To find the car’s velocity at the end of this distance, we would use the third equation of motion;
Mathematically, the third equation of motion is calculated by using the formula;
Substituting the values into the formula, we have;
<em>Final velocity, V = 18.17 m/s</em>
Therefore, the car’s velocity at the end of this distance is <em>18.17 m/s.</em>
