Explanation:
Given that,
Mass of a car, m = 1200 kg
Acceleration of the car, a = 35 m/s²
The force acting on the car is given by :
F = ma
F = 1200 kg × 35 m/s²
= 42000 N
If the force is 30,600 N, then acecleration is given by :
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{30600}{1200}\\\\a=25.5\ m/s^2[/tex]
Hence, this is the required solution.
