ANSWER:

101.08 joules.

STEP-BY-STEP EXPLANATION:

Given:

m = 0.140 kg

v = 38.0 m/s

Kinetic energy can be calculated using the following formula:

E=\frac{1}{2}\cdot m\cdot v^2

Replacing

\begin{gathered} E=\frac{1}{2}\cdot0.140\cdot(38.0)^2 \\ E=101.08\text{ J} \end{gathered}

The kinetic energy of baseball is 101.08 joules.
