Answer:
The maximum error is
Explanation:
From the question we are told that
The length is
The radius is
The pressure is
The rate is
The viscosity is
The error in the viscosity is mathematically represented as
Where
and
and
So
substituting values
For the work-energy theorem, the work needed to stop the bus is equal to its variation of kinetic energy:
where
W is the work
Kf is the final kinetic energy of the bus
Ki is the initial kinetic energy of the bus
Since the bus comes at rest, its final kinetic energy is zero:
, so the work done by the brakes to stop the bus is
And the work done is negative, because the force applied by the brake is in the opposite direction to that of the bus motion.
