A CAR HAS A MASS OF 1200KG TRAVELLING ON A LEVEL ROAD. THE CAR DECELERATED AT A RATE OF 10M/S^2 TILL THE CAR STOPPED. iT HAS TO OVERCOME A TOTAL RESISTANCE OF 400N WHILE BRAKING.
(I) CALCULATE THE BRAKING FORCE OF THE CAR
(II) WHAT WAS THE DRIVING OF CAR OF THE CAR?
The total force decelerating the car was
F = M a = 120,000 N
The numbers you have presented don't make sense.
Neither does Part II of your question
