Answer:
The correct answer will be "1477.84 N".
Explanation:
Given that,
Mass,
m = 1.6 mg
or,
= 1600 kg
Initial velocity,
u = 72 km/h
= 
= 
Final velocity,
v = 18 km/h
= 
= 
Covered distance,
s = 250 m
By using the below relation, we get
⇒ 
On putting the values, we get
⇒ 
⇒
(shows the deceleration)
Slope will be given as 1 in 25, then
⇒ 

hence,
As we know,
⇒ 
or,
⇒ 
⇒ 
On substituting all the values, we get
⇒ 
⇒
