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=
= 0.1× 27.04
= 2.704 kgm^-2s-2
Therefore, the kinetic energy of the ball is 2.704 kgm^-2s-2.
