What is the kinetic energy of a baseball moving at a speed of 45 m/s if the baseball has a mass of 0.15 kg?

1 answer

The formula to calculate the kinetic energy is given by Kinetic Energy = 1/2 * mass * velocity^2.

Given:
Mass = 0.15 kg
Velocity = 45 m/s

Plugging these values into the formula:
Kinetic Energy = 1/2 * 0.15 kg * (45 m/s)^2

Calculating:
Kinetic Energy = 0.5 * 0.15 kg * (45 m/s)^2
= 0.5 * 0.15 * 2025 kg m^2/s^2
= 151.875 kg m^2/s^2

Therefore, the kinetic energy of the baseball is 151.875 kg m^2/s^2.
