Question

kinetic energy of a body of mass 1 kg . is 200 joule its velocity is​

Answer 1

the the formula for kinetic energy is :- 1/2 mv²

here, m= mass &

v= velocity

now , putting the value in the formula

200 = 1/2 × 1 × v²

400 = v²

v = √400

we get , v = 20

so , the velocity of body is 20m/s
