Answer:F = 10800 N

Explanation:We have,

Mass of a car, m = 1200 kg

Initial speed of the car, u = 30 m/s

Finally speed, v = 0 (as it stops)

Stopping distance, d = 50 m

It is required to find the braking force. For this firstly we can find the acceleration of the car using equation of kinematics as :

Braking force is, F = maSo, the braking force is 10800 N. The correct option is A
