A 2000 kg race car is moving at a constant velocity of +30 m/s. When it gets to the finish line the driver slams on the brakes and slows to a velocity of +5 m/s in 4 seconds. What is the momentum of the race car before it hits the brakes? 60000kgm/s

What is the impulse on the race car in order to slow the car to 5 m/s? -50000kgm/s

What is the force of friction experienced by the race car while it is slowing down? *Assume this force of friction is constant and you have no applied force when you are braking* N

If the car continues to brake with the same force of friction, how long will it take for the car to come to a complete stop from the velocity of 5m/s? s
