u = 36*5/18= 10 m/s
s = 20m
v = 0
2as=v^2 - u^2
a = - 2.5 m/s^2
Force = m a = 1200 * (-2.5) N
magnitude = 3,000 N
s = 20m
v = 0
2as=v^2 - u^2
a = - 2.5 m/s^2
Force = m a = 1200 * (-2.5) N
magnitude = 3,000 N

Initial velocity (u) = 36 km/h or 10 m/s
Final velocity (v) = 0 m/s
Distance (s) = 20 m
We know'
Equation of motion
i.e 2as = v^2 - u^2
Acceleration (a) = -2.5 m/s^2
We know'
Force = mass × acceleration
= 1200 × -2.5
= 3000 N
Final velocity (v) = 0 m/s
Distance (s) = 20 m
