Final answer:
Using the momentum formula, the velocity of a baseball with a momentum of 2.1 kg·m/s and mass of 0.14 kg is calculated to be 15 m/s.
Step-by-step explanation:
To find the velocity of the baseball, we start with the equation momentum (p) = mass (m) × velocity (v). Given the momentum of the baseball is 2.1 kg·m/s and the mass is 0.14 kg, we can rearrange the equation to solve for velocity (v = p/m).
Substituting the given values into the equation, we get:
velocity (v) = 2.1 kg·m/s / 0.14 kg.
After calculating, the result is:
velocity (v) = 15 m/s.
Thus, the velocity of the baseball is 15 meters per second.
