<h3><u>Given</u><u>:</u><u>-</u></h3>

Mass,m = 0.5 kg

Velocity,v = 10 m/s

Find the kinetic energy of a ball.

<h3><u>Formula</u><u> </u><u>used:-</u><u> </u></h3>

Kinetic energy = 1/2 × m × v²

<h3><u>Solution:-</u><u> </u></h3>

We know that,

Kinetic energy = 1/2 × m × v²

★ Substituting the values in the above formula,we get:

Kinetic energy = 1/2 × 0.5 × 10²

Kinetic energy = 1/2 × 5/10 × 100

kinetic energy = 5/10 × 50

Kinetic energy = 5 × 5

Kinetic energy = 25 Joules
