The kinetic energy of the ball is 2.704 kgm^-2s-2.

Given: Mass of the ball= 200g

Velocity= 5.2m/s

To find: the Kinetic energy of the ball.

Solution:

Kinetic energy is a form of energy that is present in an object which helps the object to move when force is applied.

mass of the ball= 200g= 0.2kg

Kinetic energy=

 \frac{1}{2}m {v}^{2}

 =  \frac{1}{2} \times 0.2 \times  ({5.2})^{2}

= 0.1× 27.04

= 2.704 kgm^-2s-2

Therefore, the kinetic energy of the ball is 2.704 kgm^-2s-2.
