The acceleration of the car is 0.8049
.It takes 13.802s to travel the 230 m.
<h3>
What is acceleration?</h3>
In mechanics, acceleration refers to the rate at which an object's velocity with respect to time varies. Acceleration is a vector quantity (in that they have magnitude and direction). The direction of an object's acceleration is determined by the direction of the net force acting on it. Newton's Second Law states that the combined effect of two factors determines how much an item accelerates:
(i) It follows that the magnitude of the net balance of all external forces acting on the object is directly proportional to the magnitude of this net resulting force, and
(ii) the mass of the thing, depending on the materials out of which it is constructed, is inversely proportional to the mass of the thing.
Calculations:
40 km/hr ----- 11.11m/s
80 km/hr ----- 22.22m/s
Time taken
v-u=at
22.22-11.11= 0.8049 x t
t=13.802s

Its either B. force or A. net force but I will go with force because forces can either push or pull I hope it help you.
To solve this problem it is necessary to apply the concepts related to the Pressure which describes the amount of Force made on an area unit.
Its mathematical expression can be defined as
Where,
F= Force
A = Area
Our values are given as
With the diameter we can find the Area of the circular heel, that is
To find the force by weight we need to apply the Newton's second Law
Finally the pressure would be
Therefore the pressure that she exerts on the carpet sample is 6.788Mpa
