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.

Answer:
1913
Explanation:
<u>A hypothesis of the hydrogen atom was developed by Niels Bohr in 1913, based on the quantum theory</u>, which states that certain physical quantities can only have discrete values. Electronic particles travel about a nucleus, but only in specified orbits. If electrons jump to a lower-energy orbit, the energy difference between the two orbits is emitted as radiation.
Hope this helps explain what the answer to your question is and why it is that answer.
