Answer:
The statement is true: velocity and acceleration have opposite directions in the interval of braking.
Explanation:
Let's say we have a velocity .
The acceleration is the rate of change of the velocity . This means that if is <em>increasing during</em> time, then must be positive. But if is <em>decreasing over</em> time, then will be negative (even though the velocity is positive).
Mathematically:
decreases ⇒
⇒.

To solve the problem, we can use the Einstein's famous equivalence between energy and mass:
where
E is the energy
m is the mass
c is the speed of light
In this problem, the mass of the substance is
, so if all this mass would be converted in energy, we would have an energy of
