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.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
