56.25%

Explanation:

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

Kinetic energy is given by KE=1/2mv^2

We can also write KE as
KE=1/2mv^2=1/2(mv)^2/m=1/2p^2/m

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

p=1.25mv
KE=1/2(1.25p)^2/m=1/2*p^2/m*1.5625

So KE will increase by 56.25%
