A moving body of 30 kg has 60j of kinetic energy. Calculate the speed
Dhinu:
speed is 2 m/s (Ans.)
wow! how brilliant miss clarevincent !! u have chosen wrong ans. as the brainliest answer .. .. lol
How
it's (1/2) x m x v^2 = 60 => 30 x v^2 = 120 => v^2 = 4 => v = √4 = 2 m/s
that's the solution ...
it would be easy to explain if i got the chance to answer... but u have already choosen the wrong one as brainliest ..
oh! answers are deleted .. wait a sec.
My answer is correct but unable to type in mobile
oh! then how did u write the wrong ans.!!??
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
