K.E = 1/2 × m × v²
where,
K.E = kinetic energy of a body
m = mass of the body
v = velocity of the body
From given, we have,
K.E = 60 joule
m = 30 kg
⇒ 60 = 1/2 × 30 × v²
⇒ 2 × 60 = 30 × v²
⇒ 120 = 30 × v²
⇒ 4 = v²
∴ v = 2 m/s
hope this helps you mate..

Answer:
Hello friend,
Explanation:
A moving body of mass 30 kg has 60 joule of kinetic energy.
To find:
The speed of a body
Solution:
K.E = 1/2 × m × v²
where,
K.E = kinetic energy of a body
m = mass of the body
v = velocity of the body
From given, we have,
K.E = 60 joule
m = 30 kg
⇒ 60 = 1/2 × 30 × v²
⇒ 2 × 60 = 30 × v²
⇒ 120 = 30 × v²
⇒ 4 = v²
∴ v = 2 m/s
