Question

if kinetic energy i doubled what happen to its momentum?

Answer 1

$kinetic \: energy = \frac{1}{2} m {v}^{2} \\ kinetic \: energy = \frac{1}{2} m {v}^{2} \times \frac{m}{m} \\ kinetic \: energy = \frac{1}{2m} {p}^{2} .....p \: is \: momentum \\ k = \frac{ {p}^{2} }{2m} \\ p = \sqrt{2mk} \\ if \: k \: becomes \: 2k \: then \\ \\ p = \sqrt{2m(2k)} \\ p = \sqrt{2} \times \sqrt{2mk}$


✨✨Hence, momentum increase by √2 Times.✨✨

Answer 2

.......... Now get your brainliest answer..........

If kinetic energy is doubled then ,
since we know that,

K.E=1/2*m* v^2 *2=mv^2=(mv)*v=momentum*v.

means momentum will increase v times after doubling the K.E.
