* Moles are a unit of amount, not speed. Moles are used to measure the quantity of a substance. They're not a measure of how fast something is moving.
* Speed is measured in meters per second (m/s). This tells us how much distance an object covers in a given amount of time.
Here's how to calculate the kinetic energy of the softball:
1. Understand the Formula:
* Kinetic Energy (KE) = (1/2) * mass * velocity²
2. Identify the Values:
* Mass (m) = 0.13 kg (assuming the softball has the same mass as a baseball)
* Velocity (v) = 30 m/s (replace the incorrect "moles per second" with a proper speed unit)
3. Calculate the Kinetic Energy:
* KE = (1/2) * 0.13 kg * (30 m/s)²
* KE = 0.5 * 0.13 kg * 900 m²/s²
* KE = 58.5 Joules (J)
Therefore, the kinetic energy of the softball traveling at 30 m/s is 58.5 Joules.
