148772 A vehicle accelerates from speed ' $v$ ' to ' $2 \mathrm{v}$ '. Work done during this is

1 less than the work done in accelerating it from rest to $\mathrm{v}$.
2 four times as the work done in accelerating it from rest to $v$.
3 same as the work done in accelerating it from rest to $\mathrm{v}$.
4 three times as work done in accelerating it from rest to $\mathrm{v}$.
