Ke = (1/2)(m)(v^2)
Ke = (1/2)(1451kg)(48^2)
Ke = 1,671,552 joules

Ke = (1/2)(1451)(24^2)
Ke = 417,888

1/4th the energy

We know, kinetic energy is directly proportional to the square of velocity, So, if kinetic energy is halved it's velocity will reduce to its 1/4th value

In short, Your Answer would be 1/4

Hope this helps!

If an object is moving eastward and slowing down, then the direction of its acceleration vector is
iragen [17]
It would still be eastward because The direction of the velocity vector is always in the same direction as the direction which the object moves.
