Answer 1

Step-by-step explanation:

Given:-

Mass of body ,m = 10Kg

Velocity ,v = 5m/s

To Find:-

Kinetic Energy ,KE

Solution:-

As we know that the energy possess by body due to its motion is called Kinetic Energy.

• KE = 1/2mv²

Where,

KE is the Kinetic Energy

m is the mass

v is the speed/velocity

Substitute the value we get

→ KE = 1/2×10×5²

→ KE = 1/2× 10×25

→ KE = 250/2

→ KE = 125 J

Therefore, the kinetic energy of the body is 125 Joules..

Hence, Option (b) 125 J is the correct answer .
