Question #db371

Answer 1

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%
