A car is going 8 meters per second on an access road into a highway and then accelerates at 1.8 meters per second squared for 7.2
seconds. How fast is it then going?

20.96 m/s is the final speed.

Step-by-step explanation:

Given that:

Initial speed of the car = 8 m/s

Acceleration of the car = 1.8 m/

Time for which the car accelerates = 7.2 seconds

To find:

The speed of car after accelerating for 7.2 seconds at an acceleration of 1.8 m/ = ?

Solution:

First of all, let us have a look the formula given for the final velocity of an object with given initial speed, acceleration and time:

Where is the final speed of object

is the initial speed of an object

is the acceleration of object and

is the time

Here,

and

To find:

Let us put all the given values in the formula:

So, the answer is:

20.96 m/s is the final speed.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
