Hi...
Initial velocity = 36 km/h =10 m/s
Final velocity = 0 m/s
Time = 5 sec
According to the first equation of motion, v = u + at
0 =10+a×5
a = -2 m/s2
The forces to stop both the car in 5s = ma= 1000×2 = 2000 N
The forces to stop both the bus in 5s = = ma= 8000×2 = 16000 N..
Hope this helps u!!

saiyyam:
2000*-2=-4000N
and the same for bus rest is correct
