Question

A body of mass 10kg moving with a velocity of 5m/s find the kinetic energy of a body​

Answer 1

Answer:

Given:

Mass= 10kg

Velocity= 5m/s

To find:

Kinetic Energy=?

Solution:

We know,

KE=1/2 mv^2

KE= 1/2×10×25(5×5)

KE= 500J

Answer 2

$kinetic \: energy \: = \frac{1}{2} m {v}^{2}$

given that m = 10 kg and v = 5 m/s.

substituting this in question, we get

$kinetic \: energy = \frac{1}{2} \times (10)( {5}^{2} )$

$= 5 \times {5}^{2}$

$= 125$
