Given point:
Calculating the area:
given that initial speed of the car is
now after travelling the distance d = 1.8 * 10^1 m the car will stop
so here we can use kinematics to find the acceleration of car
here we have
net force applied due to brakes of car is given by Newton's II law
here we have
mass = 1.2 * 10^3 kg
now we can say
So the force applied due to brakes is given as above
