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
