Answer:
50.97 m
Explanation:
m = Mass of truck
= Coefficient of static friction = 0.4
v = Final velocity = 0
u = Initial velocity = 72 km/h =
s = Displacement
Force applied
Frictional force
Now these forces act opposite to each other so are equal. This is valid for the case when the load does not slide
Since the obect will be decelerating the acceleration will be
From the kinematic equations we have
So, the minimum distance at which the car will stop without making the load shift is 50.97 m.
