A 1000-kg car moving at 10 m/s brakes to a stop in 5 s. The average braking force is? On this question I asked my teacher I am suppose to get 2000 N and I don't get how to get it.

1 answer

you are right it is 2000 N. cuz, you can compute the acceleration by noting that the acceleration is the change in time.

a= (10 m/s-0 m/s)/5 s=m/s^2
