The stopping distance is 45.0 m
Explanation:
First of all, we find the acceleration of the truck, by using Newton's second law:
where
is the net force on the truck
is the mass of the truck
a is its acceleration
Solving for a,
where the negative sign means the acceleration is opposite to the direction of motion.
Now, since the motion of the truck is at constant acceleration, we can apply the following suvat equation:
where
v = 0 is the final velocity of the truck
u = 22.2 m/s is the initial velocity
is the acceleration
s is the stopping distance
And solving for s,
