1. The problem statement, all variables and given/known data A coasting car with a mass of 1000 kg has a speed of 100 km/h down a 10 degree slope when the brakes are applied. if the car is slowed to a speed of 50 km/ h in 8s, compute using the impulse-momentum equation the average of the total braking force exerted by the road on all the tires during the period. Treat the car as a particle and neglect air resistance. 2. Relevant equations 3. The attempt at a solution The impulse-momentum equation states that the sum of Forces F = mdv/dt so we turn this equation into an integral and solve, I know that the answer is 3400 N but do not know how to get it. any help?
