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.
Answer:
Its acceleration is certainly negative.
Explanation:
- When an object moving in a straight line decelerates then its velocity certainly decreases.
- Its acceleration is certainly negative.
- As we know that acceleration is the rate of change in velocity and the object is decelerating i.e. its velocity is reducing with time.
where:
are final and initial velocities of the object
are final and initial time of observation.
- Its SI unit is
