Answer 1

15/2.5= 6 miles per second

Answer 2

Acceleration, a = 6 m/s²

Step-by-step explanation:

It is given that,

Initial velocity of car is 0 at it starts from rest.

Final velocity of car, v = 15 m/s

Time taken by the car, t = 2.5 s

We have to find the acceleration of the car. It is defined as the rate of change of velocity. Mathematically, it can be written as :

`a=(v-u)/(t)`

`a=(15\ m/s-0)/(2.5\ s)`

a = 6 m/s²

So, the acceleration of the car is 6 m/s². Hence, this is the required solution.
