56.25%

Explanation:

Momentum is defined as mass times velocity, or p=mv

Kinetic energy is given by KE=12mv2

We can also write KE as
KE=12mv2=12(mv)2m=12p2m

So if we take the above equations as the position before the increase, then increase momentum by 25%:

p=1.25mv
KE=12(1.25p)2m=12p2m1.5625

So KE will increase by 56.25%
