Yes, I know the answer is 4000N, and the solution is there, I got the answer wrong in my test paper, I nned to know why the correct answer is 4000N.
The given solution was:
20 m/s divided by 5 seconds = 4m/s2
Force= ma= 1000 X 4 = 4000N
I need someone to explain step-by-step...
I need help with my Physics Homework!
A Car of mass 1000kg decelerates from 20m/s2 to rest in a time of 5 seconds. Calculate the braking force of the car, assuming that there is no friction.
Ans:
20 m/s2 / 5 seconds = 4m/s2
Force= ma= 1000 * 4 = 4000N
Can anyone explain this to me?
