2. Justin is driving at a constant velocity of 22.6 m/s eastbound in his 945-kg car on a rough road. Suddenly, he sees a raccoon in the street, so he slams on the brakes. His brakes exert a force of
100 N on the wheels.

a. Draw and Label a FBD before the brakes are applied.

b. Calculate the net force

C. Calculate the acceleration of the car once the brakes are applied.

explanation:

its math

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

it's a b and
