Question

A body having velocity of 2 m/s has a KE of 1 J. Mass of the body is ------

Answer 1

Answer:

kinetic energy:

1/2 X mass X velocity

given kinetic energy=1joule

velocity of the body=2m/s

$\</strong><strong>b</strong><strong>l</strong><strong>u</strong><strong>e</strong><strong>{</strong><strong>1</strong><strong>j</strong><strong>o</strong><strong>u</strong><strong>l</strong><strong>e</strong><strong>=</strong><strong>1</strong><strong>/</strong><strong>2</strong><strong>X</strong><strong>M</strong><strong>X</strong><strong>2</strong><strong>m</strong><strong>/</strong><strong>s</strong><strong>}$

$\</strong><strong>g</strong><strong>r</strong><strong>e</strong><strong>e</strong><strong>n</strong><strong>{</strong><strong>1</strong><strong>k</strong><strong>g</strong><strong>=</strong><strong>Mass</strong><strong>}$
