In the Force lab, we use a small lab car with mass m=5 Kg, the experiment is on a horizontal table, on the car is acting a pulling force F= 20 N and the kinetic friction force Fr is acting as well. The car initially is at rest, and take 6.0 seconds to reach the velocity of 8.5 m/s.

a)       Calculate the magnitude of the friction force Fr acting on the car?

b)      We remove the pulling force when the car reaches the velocity of 8.5 m/s. What will be the total distance travelled by the car before stop? (From t=0 seconds until stop)

c)       What is the kinetic coefficient of friction?
