Sagot :
Braking force is applied to brakes to stop the car. The average braking force is 2kN.
What is force?
Force is the product of mass of the object and acceleration.
The braking force is the force applied on the brakes to stop the car at a distance.
Suppose, the mass of the car is m=1000kg
The initial velocity of the car is u=10m/s
The time is t=5s
The final velocity of the car is v = 0 m/s
Applying the first equation of motion, to calculate the acceleration,
v=u + at
a=(v−u) / t
a =0−10 / 5
a =−2m/s²
Then, apply Newton's Second Law of Motion to calculate the braking force
F = ma = 1000 x 2= 2000 N or 2kN
Thus, the magnitude of the average braking force on the car is most nearly 2kN.
