Question

Calculate the kinetic energy of a body of mass 2kg moving with velocity of 0.2 m/sec.

Answer 1

kinetic energy (K) = 1/2 mv2

=> 1/2 * 2 *0.2 *0.2
=> 0.04

therefore, kinetic energy of the body is 0.04 kg m/s

Answer 2

Hello,

Mass of the object = 2kg

Velocity of the object = 0.2 m/sec

We need to find the kinetic energy of the block.

The energy possessed by any object due to its motion is known as kinetic energy of the object.

The formula for kinetic energy is
$\frac{1}{2} m {v}^{2}$
Where

M is the mads of the object
And,
V of the velocity at which the object is moving.


So,. The answer is...
$\frac{1}{2} \times 2 \times {0.2}^ {2} = \frac{1}{2} \times 2 \times 0.04 \\ = 0.04 \: kgm \: per \: second$


Hope this will be helping you ✌️
