Question

Momentum of a particle of mass m is p its kinetic energy will be

Answer 1

k(kinetic energy) = 1/2 mv^2

p=mv

what must we do to p to make it 1/2 mv^2?

first, to get v^2, what if we do p^2

p^2=m^2 v^2

now that we have v^2, we need to do something to the rest of it.

to get m instesd of m^2,

p^2/m=mv^2

now we just have to divide the above by 2 to get 1/2 mv^2

hence, your answer: p^2 / 2m

thanks

Answer 2

momentum = mass* velocity i.e. momentum=mv

kinetic energy=1/2 mv square

if mv will be p then kinetic energy will be 1/2p square

hope it helps!!!!!!!
