Answer:

Step-by-step explanation:
Given
--- acceleration
--- final velocity
--- initial velocity (it is 0, because the car starts from rest)
Required
Determine the time taken
This will be solved using Newton's first equation of motion:

Substitute values for v, u and a



Make t the subject


<em>Hence, the time taken is approximately 5.2 seconds</em>
Answer:

Step-by-step explanation:
Let's start by using distributive multiplication:

So:

Grouping like terms:

Now,
is equal to:

In this sense:

In order to satisfied the equality:

Hence, from (1), let's solve for a:

And from (2), let's solve for b:

Let's verify the result evaluating the values of a and b into the original equation:

As you can see, the values satisfy the equation, therefore, we can conclude they are correct.
