Question

-An object of
mass 2 kg is moving with a
Velocity of 25 m/s. Calculate it's kinetic Energy​

Answer 1

Since Kinetic Energy formula is=1/2mv²

K.E=1/2×2×(25)²

=625J

Answer 2

Given :-

• Mass of object (m) = 2 kg
• Velocity of object (v) = 25 m/s

To Find :-

• It's kinetic energy.

Solution :-

As we know that,

$\red\bigstar$ K.E = 1/2 × mv²

Where,

• K.E = Kinetic energy
• m = Mass
• v = Velocity

[ Putting values ]

$\implies$ K.E = 1/2 × 2 × 25²

$\implies$ K.E = 1 × 625

$\implies$ K.E = 625 J $\green\bigstar$

Hence,

• The kinetic energy of an object is 625 J.

For information:

• P.E = mgh
• M.E = K.E + P.E
