The acceleration of the car is 6.86 m/s² and the time taken for the car to stop is 3.64 s.
The given parameters;
- mass of the car, m = 1400 kg
- Initial velocity of the car, u = 25 m/s
- coefficient of kinetic friction, μ = 0.7
The acceleration of the car is calculated as follows;
a = μg
a = 0.7 x 9.8
a = 6.86 m/s²
The time taken for the car to stop is calculated by using Newton's second law of motion;
F = ma
Thus, the acceleration of the car is 6.86 m/s² and the time taken for the car to stop is 3.64 s.

Explanation:
From the question we are told that
The angle at which the string is maintained is 
The length of string reeled in is 
Using the SOHCAHTOA formula
We have that the hypotenuse(Hyp) is l = 152
Hence the horizontal displacement of the kite which is the Adjacent(Adj) can be evaluated as
substituting values
