Answer 2

To find the initial velocity, final velocity, and acceleration of a car moving with uniform acceleration, we can use the following equations of motion:

1. Initial velocity (u): The initial velocity can be found using the equation: ``` u = v - at ``` where: - u is the initial velocity, - v is the final velocity, - a is the acceleration, and - t is the time.

2. Final velocity (v): The final velocity can be found using the equation: ``` v = u + at ``` where: - v is the final velocity, - u is the initial velocity, - a is the acceleration, and - t is the time.

3. Acceleration (a): The acceleration can be found using the equation: ``` a = (v - u) / t ``` where: - a is the acceleration, - v is the final velocity, - u is the initial velocity, and - t is the time.

Now let's apply these equations to the given problem.

Given: - Final velocity (v) = 30 m/s - Time (t) = 3 s - Initial velocity (u) = ?

Finding the Initial Velocity (u):

Using the equation `u = v - at`, we can substitute the given values to find the initial velocity: ``` u = 30 m/s - a * 3 s ```

Finding the Final Velocity (v):

Using the equation `v = u + at`, we can substitute the given values to find the final velocity: ``` 30 m/s = u + a * 3 s ```

Finding the Acceleration (a):

Using the equation `a = (v - u) / t`, we can substitute the given values to find the acceleration: ``` a = (30 m/s - u) / 3 s ```

Now, let's solve these equations to find the values of the initial velocity, final velocity, and acceleration.

Please note that I will need to perform calculations to find the exact values. Give me a moment.
