1. Convert units:

* Mass: 62.0 g = 0.062 kg (1 kg = 1000 g)

* Velocity: 150 km/h = 41.67 m/s (1 km = 1000 m, 1 hour = 3600 seconds)

2. Apply the kinetic energy formula:

Kinetic Energy (KE) = (1/2) * mass * velocity²

3. Plug in the values:

KE = (1/2) * 0.062 kg * (41.67 m/s)²

4. Calculate:

KE ≈ 54.1 Joules (J)

Therefore, the kinetic energy of the tennis ball is approximately 54.1 Joules.
