A moving body of 30 kg has 60j of kinetic energy. Calculate the speed

Dhinu: speed is 2 m/s (Ans.)

Dhinu: wow! how brilliant miss clarevincent !! u have chosen wrong ans. as the brainliest answer .. .. lol

Clarevincent: How

Dhinu: it's (1/2) x m x v^2 = 60 => 30 x v^2 = 120 => v^2 = 4 => v = √4 = 2 m/s

Dhinu: that's the solution ...

Dhinu: it would be easy to explain if i got the chance to answer... but u have already choosen the wrong one as brainliest ..

Dhinu: oh! answers are deleted .. wait a sec.

nanimuvva: My answer is correct but unable to type in mobile

Dhinu: oh! then how did u write the wrong ans.!!??

Dhinu: next time check the solution carefully and then choose it as the brainliest one if it's right ... @clarevincent

Answer:

Mass(m)=30kg

Velocity (v)=?

Kinetic energy (Ek)=60J

Ek = 1/2mv²

60= 1/2 × 30+v²

60= 15v²

60/15=v²

v²=4

v= √4

v=2m/s or 2 ms·¹

Hope it helped u ✌

mark as brainliest and follow
