Question

If mass, speed and linear momentum of a particles are m,v and p respectively, then kinetic energy of a particles is....

Answer 1

Answer:

p.dv=dk

Explanation:

since since p is momentum v is velocity nothing but speed ki is kinetic energy

Answer 2

Answer:

k= 1/2 mv^2

Explanation:

as we know:

$p = \sqrt{2mk}$

by this expression we get :

p^2=2mk

k=p^2/2m
