Final answer:
The kinetic energy of the tennis ball is 0.029 Joules.
Step-by-step explanation:
To calculate the kinetic energy of a tennis ball, we can use the formula:
Kinetic Energy = (1/2) x mass x velocity²
Given that the mass of the tennis ball is 58 g (or 0.058 kg) and the velocity is 30 m/s, we can substitute these values into the formula:
Kinetic Energy = (1/2) x 0.058 kg x (30 m/s)²
Simplifying the calculation, we get:
Kinetic Energy = 0.029 J
Therefore, the kinetic energy of the tennis ball is 0.029 Joules.
