Question

a body of mass 5 kg has a velocity of 2 m/s .then kinetic energy will be​

Answer 1

Answer:

10 joule

Explanation:

here we know that the object has initial velocity=2m/s and the mass of object=5kg

K.E.=1/2mv2

=1/2×5×4

=10 joules

Answer 2

Answer :

Given -

• Mass = 5 kg
• Speed = 2 m/s

To Find -

Kinetic energy ?

Solution -

Kinetic Energy = ½mv²

Now, Calculating Kinetic energy :

⇒ ½*5*(2)²

⇒ 5*2

⇒ 10 J

Hence, Kinetic energy of the body is 10 J.

Some Additional Information -

• Energy possessed by a body due to change in position of shape is called potential energy.

• Energy possessed by a body due to change in motion is called Kinetic energy.

• PE = mgh

• KE = ½mv²
