Question

Hola brainlics
solve my question ;)


Kinetic energy of a body of mass 2 kg moving with a speed of 10 m/second square, is​

Answer 1

Answer:

• The formula for Kinetic Energy is ½mv².

We are given :

• Mass = m = 2 kg
• Speed = v = 10 m/s

Hence, using the given information :

• ⇒ ½(2)(10)²
• ⇒ (10)²
• ⇒ 100 J ✔

• Hence, the Kinetic energy of the body is 100 J.

More Information :-

• Energy is said to be the capacity of doing work.
• Kinetic energy of a body is the energy that it possesses due to its motion.
• Potential energy of a body is the energy that it possesses due to its rest position.
• Formula of Kinetic energy : ½mv²
• Formula of Potential energy : mgh

Answer 2

Answer:

mass=2kg

speed=10m/second

kinetic energy= 1/2×2×10²

kinetic energy=100j
